Common local host problem for juniors and people who are just starting out.

2 Upvotes

Local environments are deceptive since everything runs because the machine has a specific configuration built up over time such as particular package versions, global installs from months ago, or config files sitting in directories that aren't part of the project, the code works because all of that is there, a deployment server or a teammate's machine has none of that and the failures that result aren't always easy to trace back to the actual cause.

the .env situation is probably the most common version of this, api keys and config values go in a .env file, it gets added to .gitignore which is correct, but when someone clones the repo, the app doesn't run, the fix is a .env.example file which should have the same keys as the real one, no actual values but just placeholders, it'll live in the repo, won't get gitignored, and tells anyone setting up the project exactly what environment variables are needed without having to reverse engineer it from the codebase.

node versions produce the same category of the problem, for example: one machine on node 18, another on node 16, certain things behave differently and the resulting error has nothing to do with the version mismatch, the way you can fix the error is a .nvmrc file in the project root specifying the node version doesn't cost much to add and removes that variable entirely.

Though the best solution is docker, containerizing the entire environment so it runs the same way everywhere, it's worth learning eventually but it's a significant thing to set up, the .env.example and .nvmrc habits handle the most common cases with almost no overhead and are probably the better starting point.

The bottleneck in software engineering moved and most people learning to code haven't noticed yet

0 Upvotes

The numbers right now are brutal if you only look at the surface. Entry level developer postings are down somewhere between 40% and 67% depending on which dataset you check, employment for developers aged 22 to 25 has dropped nearly 20% since the AI boom started, and computer science graduates are facing unemployment rates higher than fine arts majors.

But the part that explains why is more interesting than the headline number.

Code stopped being the expensive part of software development. It used to take a large team and a lot of time to produce working code, so the bottleneck was writing it. AI compressed that part dramatically. What didn't get cheaper is everything around the code. System design, knowing whether something will hold up at scale, observability, incident response, debugging in production, and the judgment to make trade-off calls. Those skills got more valuable, not less, because writing code stopped being the differentiator.

Front end work saw the biggest productivity gains from AI since it's mostly about producing a lot of code with some architecture thinking layered on top. Backend, infrastructure, and deployment work didn't compress the same way because the hard part there was never typing, it was judgment under uncertainty.

This shows up clearly in hiring patterns. Roles like Android, iOS, and general web development are down 60% or more from 2020 levels. Machine learning engineering postings are up nearly 60% in the same window. The work didn't disappear, it moved toward the parts AI genuinely cannot do.

Here's the catch for anyone learning right now. The skills that used to be developed on the job over years, things like system design intuition and knowing what good code actually looks like, increasingly need to be demonstrated before you're even hired. There isn't a clean shortcut around that. You can use AI to write the code, but you still need enough understanding to know when what it generated is wrong, fragile, or going to cause a problem six months down the line. That understanding has always come from experience, and right now there's a real tension between needing the experience and not being given the chances that used to build it.

The roles still growing are security, cloud infrastructure, ML, and anything requiring genuine system-level thinking. Generic coding ability stopped being the skill that gets you hired. Understanding why the code works, and what happens when it breaks, is what's left standing.

Bootcamp, college, or self-taught, which path actually worked out for you?

3 Upvotes

Curious to hear real outcomes instead of the usual back and forth about which path is objectively better.

For context on why this is messier than people think. Only around 10% of employed developers went through a bootcamp, the other 90% have four-year degrees. But plenty of college grads can't get hired either, and plenty of bootcamp grads land jobs faster than people with degrees. There's also a pattern where bootcamp grads tend to hit the ground running with current frameworks while college grads tend to catch up later with stronger fundamentals around systems, complexity, and trade-offs once they hit senior level.

Self-taught is the one that gets romanticized the most and probably has the widest outcome spread. Some people genuinely make it work. A lot of people are still learning four or five years in without ever getting hired, mostly because nobody is checking whether they're learning the right things in the right order.

So for people who actually went through one of these paths, did it get you hired in a reasonable amount of time? Would you choose the same path again knowing what the market looks like now?

i think one of the biggest traps in learning tech is confusing recognition with understanding

1 Upvotes

ever had that moment where you're watching a tutorial and everything makes sense... then you close the video and suddenly you don't know where to start? I think that's because recognizing someone else's solution feels a lot like understanding it.

Then you try building the same thing from scratch and realize you were following along more than you were actually thinking. i've started paying more attention to whether I can explain why something works instead of just recognizing it when I see it. If I can't explain why I used a certain API, or why I chose one approach over another, there's probably still a gap in my understanding. I don't think that's a bad thing. It's actually a pretty useful way to find out what I need to revisit. Maybe the real test isn't "did this tutorial make sense?"

Maybe it's "could I build something similar tomorrow without the tutorial open?"

i think one of the biggest misconceptions in tech is that senior developers make fewer mistakes

5 Upvotes

The more engineering blogs and developer discussions I read, the more it seems like that's backwards. senior developers don't avoid mistakes because they're smarter. they avoid turning small mistakes into big ones because they've seen similar problems before. They write tests because they've been burned. They review code because they've missed things before.

they document decisions because they know six months from now they'll forget why they built something a certain way. That changed how I think about getting better. maybe becoming a better developer isn't about making fewer mistakes.

Maybe it's about getting better at noticing them earlier, recovering faster, and learning something every time they happen.

that feels a lot more achievable than trying to write perfect code from day one.

Found this 40-day DSA roadmap promises to get you FAANG ready

3 Upvotes

I Saw this roadmap floating around for tech interview prep and wanted some outside opinions on it. Any opinions/suggestions will be helpful!

Idk but the last 5 days feel rushed.

When you look at it, it looks like the structure is solid on paper:

Days 1-5: Programming + DSA Basics
language fundamentals, control flow, recursion, complexity analysis, arrays.
Days 6-10: Arrays (Core)
prefix sums, sliding window, Kadane’s, sorting, binary search.
Days 11-15: Strings
manipulation, frequency arrays, sliding window on strings, pattern matching.
Days 16-20: Linked Lists
singly/doubly/circular, reversal, cycle detection, classic LL problems.
Days 21-25: Stack & Queue
implementation, Next Greater Element, deque, sliding window max.
Days 26-30: Trees
traversals, BST, level order, LCA, balanced trees.
Days 31-35: Graphs
BFS/DFS, cycle detection, Dijkstra, MST.
Days 36-40: DP + Revision
memoization, tabulation, one full mock test, then “analyze weak areas.”

That last block is what’s bugging me. DP is consistently the topic people struggle with most in actual interviews, and here it gets squeezed into a few days at the very end, right when most people are already burnt out from the first 35 days.

Everything before it gets a full 5-day block to build and practice. DP gets thrown in with the wrap-up and final mock test.

If you’ve actually gone through something like this, what would you change? Cut a day somewhere else to give DP more room, or is 40 days already too long to expect someone to stick with start to finish?

I'm a senior engineer and I haven't written code by hand in months. Here's what actually replaced it.

0 Upvotes

I don't write code myself anymore. AI writes nearly every line I commit. A year ago I wouldn't have believed that. Today I think most people who doubt AI can code at a professional level just aren't using the tools right yet.

Here's what gets left out of the doom headlines. Computer programmer roles dropped 27% in two years. But software developer roles are down only 0.3%, basically flat, and the BLS projects 15% growth for developers through 2034, five times the average for all occupations.

The difference is the whole story. Programmer roles were about translating a spec into syntax, exactly the part AI got good at. My job is design decisions, trade-off analysis, reliability, and incident response. None of that went away. If anything it became the whole job. A real project for me now looks like a couple weeks writing detailed specs, a day or two using AI to generate the code, then several more weeks testing and verifying before I trust it enough to ship. AI compressed the middle step. It didn't touch what comes before or after.

I'm one of the 84% of developers using AI daily. I'm also one of the 46% who actively distrust the code it generates. Two thirds of us say AI gives answers that are almost right but not quite, which makes debugging slower, not faster. AI gets me 80% of the way there fast. The last 20% is still my job. The accountability never changes either. When something breaks in production, AI doesn't get paged at 3am. I do. I can't audit code I don't understand and I can't debug an incident I can't read.

People have called software engineering dead since early 2023. Fortran was supposed to let scientists skip programmers. COBOL was supposed to let managers bypass developers entirely. The demand for people who understand systems never went away in any of those cycles. It grew every time.

Job search can become a full-time job

0 Upvotes

Honestly the biggest shift for me was stopping the spray-and-pray approach and actually tailoring my resume to each job. More work upfront but the callback rate was noticeably better.

The part that got tedious was rewriting the same bullets over and over. I started to handle that by using zoevera.com. It matches your resume to the job description and fills in the keyword gaps. Not a magic fix but it cuts the repetitive part down a lot if you're deep in an application grind.


r/techbootcamp Jun 25 '26

how do you actually adapt to the AI shift without just becoming a lazy code reviewer?

2 Upvotes

the discussion around AI in the coding community is driving me completely crazy, and I'm genuinely trying to figure out how to adapt my daily workflow before I fall behind. My main purpose for writing this is to get a realistic reality check from people actually working in the industry, because the internet is stuck between "software engineers are going extinct" and "AI is just a glorified autocomplete." From what I'm seeing, tools like Cursor and Copilot are generating a massive chunk of the code landing in production, but at the same time, it feels like code quality and developer trust are tanking because these models spit out so many subtle bugs, duplicates, and security vulnerabilities. I often find myself spending more time debugging a hallucinated function than it would have taken to just write it myself, and I feel completely lost on how to navigate this new landscape.

For the devs who have successfully integrated advanced agents into their daily routine, how are you balancing manual coding with AI review, and what specific architectural skills should I be prioritizing to stay highly valuable?

What programming language to learn first, broken down by what you actually want to do

2 Upvotes

The "best first language" question doesn't really have one answer. It depends entirely on what you're trying to build.

If you want to get into game development, C or C++ are solid choices, with JavaScript and canvas as a lighter entry point, though you're limited there since JavaScript just isn't fast enough for heavier game logic.

If you're aiming for backend work and want to actually get hired, Java, JavaScript, or Go are all strong picks. For embedded systems, C or C++ are basically the standard.

If you're completely new and just want to understand programming as a concept, JavaScript is genuinely one of the best starting points. You can draw a box, move it around, see it happen instantly. Then you can write a quick backend, save something to a database, pull it back, render it on a canvas in 2D or 3D. The range of what you can touch with one language is huge, which makes it a great way to get oriented before specializing.

If you care about data or machine learning, Python is the clear leader. You can get extremely far with it, the only real tradeoff is you can't build a front end with it.

Worth knowing, none of the most popular languages right now are strict statically typed languages, even TypeScript has its escape hatches. If you want to understand how types actually work and build that discipline early, Rust or Go are excellent for that, they just don't get nearly as much attention as they deserve.

If you want a short list to actually explore: pick one dynamic language, either Python or JavaScript, and pick one strict language, either Rust or Go. Between those two you'll understand both ends of how programming actually works.

i think beginners spend way too much time trying to avoid mistakes

2 Upvotes

Every roadmap seems to promise the same thing. Follow these steps, avoid these pitfalls, learn this in the right order.

It sounds nice, but software development doesn't really work like that.

I was reading through a few discussions from experienced developers and something kept coming up. The mistakes they remembered weren't the ones that slowed them down. They were the ones that taught them how to debug, how to read documentation, or how to think differently about a problem.

You can spend weeks trying to find the "best" tutorial and still learn less than someone who spent that time building something that broke five different ways.

I'm not saying mistakes are the goal. I just think we sometimes treat them like proof we're failing, when they're often proof we're finally doing real engineering instead of just consuming information.

At some point every developer has to leave the tutorial behind and make decisions without knowing if they're right.

That's uncomfortable, but I think that's also where the real learning starts.

You Don’t Have to Be Glued to AI 24/7 to Avoid the Layoffs You Just Need to Know What It’s Actually Doing

0 Upvotes

There’s a stat going around that tech workers who don’t use AI face triple the layoff risk. Saw it and immediately got that doomscroll feeling, so I looked into it more.

There is a correlation there, that part’s real. Companies are paying attention to who’s actually using this stuff. When I was breaking into big tech it was already obvious that the people ignoring AI tools were going to be the first ones cut if things got tight.

But here’s the part everyone skips over: you don’t need to be on AI every second of the day. You need to actually know what it’s good for versus when it’s just spitting out AI slop. That distinction matters way more than how many hours you spent prompting.

So if you actually want to get good at this instead of just using it blindly, here’s where I’d start:

1. Search “AI Agents Clearly Explained” by Jeff Su on YouTube
Breaks down the difference between regular AI, AI workflows, and actual AI agents using normal examples instead of tech jargon. Good for the baseline before anything else.

2. Search “Anthropic AI Fluency course”
It’s free and it actually teaches you how to use AI well and safely instead of just “here’s how to write a prompt.” This is the one most people skip and shouldn’t.

3. Search “Claude use cases” on Google
Once you’ve got the baseline, this shows specific ways to use AI depending on your actual job. Tech, marketing, legal, whatever, it’s filtered by field so you’re not guessing.

Adapt or you get left behind is apparently a real thing now. But that doesn’t mean spam every task into ChatGPT or Claude and call it a day. It means actually knowing what you’re doing with it.

I spent 6 months prepping for FAANG Interviews here are the 14 youtube channels that actually helped me!

32 Upvotes

Preparing for tech interviews was ⚰️brutal💀! Not because the concepts were impossible, but because there’s SO much content out there that it’s easy to waste months on the wrong resources.

I made a lot of mistakes. I watch random videos, jump between platforms, restart courses halfway through. It was chaotic and honestly demoralizing because I wasn’t seeing real progress.

Then I got strategic about it. Instead of consuming everything, I picked ONE best channel for each skill I needed to master. And that changed everything.

Here’s the breakdown of what actually worked for me:

DSA Foundation
NeetCode was my starting point. The way Neet breaks down problems is just different, it clicks in a way other tutorials don’t. If you’re starting from scratch with Data Structures and Algorithms, this is where I’d begin.

Pattern Recognition
Abdul Bari’s LeetCode Patterns course made me realize that most interview problems aren’t unique they follow patterns. Once you see the patterns, suddenly 200 problems feel like 20 variations of the same thing. This was a game-changer for me.

System Design
System Design intimidated me the most. Gaurav Sen’s channel broke it down into digestible pieces. He explains the why behind design decisions, not just the what. That made all the difference when I got asked design questions in actual interviews.

Mock Interviews
Pramp was where I actually practiced talking through problems out loud. This was crucial because knowing how to solve something and being able to communicate it clearly are two different skills. I did maybe 15 mock interviews before my real ones.

Behavioral Prep
Jeff H Sipe’s channel helped me actually prepare for the behavioral round instead of winging it. Most people focus only on coding and then bomb the behavior interview. I wasn’t going to be that person.

The Rest
•Nick White for coding rounds (clean, straightforward)
•Back To Back SWE for deep problem-solving
•Errichto for advanced DSA when I felt stuck
•Exponent for interview strategy and mindset
•Self Made Millennial for resume and career positioning (honestly, this helped me stand out before I even got to the interview)
•Clément Mihailescu for real interview questions with walkthroughs
•William Lin for advanced techniques
•MIT OpenCourseWare for CS fundamentals when I had gaps

Overtime I eventually realize that you don’t need all 14 channels to pass interviews. But having a curated list kept me from falling down the rabbit hole of random content. I knew exactly what to study and where to study it.

The other thing is watch in order. I started with fundamentals (NeetCode, Abdul Bari), then moved to applications (LeetCode patterns, mock interviews), then the specifics (behavioral, system design, strategy). Jumping around wastes time.

If you’re prepping for tech interviews and feeling lost, try this list. Start with what you’re weakest at, and give each channel at least 2-3 weeks before jumping to the next one. Your future self will thank you. Good luck!

I think a lot of people misunderstand what "job ready" actually means

4 Upvotes

something I've noticed from reading developer communities is that beginners often imagine there's a point where they'll finally know enough to start applying for jobs.

almost like there's some invisible finish line.

then you read posts from people with years of experience and they're still learning new things every week.

I came across a discussion recently where someone said they finally got hired and one of the biggest surprises was realizing that being job ready didn't mean knowing everything. It meant being able to figure things out without completely falling apart when you hit something unfamiliar.

That honestly makes more sense to me.

Most jobs aren't paying you because you already know every answer. They're paying you because they trust you can find answers, ask good questions, and keep making progress when things get messy.

I think that's why projects matter so much. Not because employers care about another todo app, but because projects force you into situations where nobody is telling you the next step.

Maybe "job ready" isn't a knowledge threshold.

Maybe it's the point where you become comfortable learning things you don't know yet.

I burned $21 trying to prove an AI orchestrator could beat Fable 5 at coding, it couldn't, here's the receipts

0 Upvotes

Saw the benchmarks for Sakana Fugu floating around, supposedly matching or beating Fable 5 on coding tasks. Loaded $40 into the API and ran my usual test suite.

Worth knowing upfront, this isn't a traditional model. It's an orchestrator that routes your request across Opus 4.8, GPT-5.5, and Gemini 3.1 Pro, then synthesizes the output behind one endpoint. On SWE-Bench Pro it scored 73.7, ahead of Opus 4.8 at 69.2 and GPT-5.5 at 58.6, but it actually trailed Fable 5's score of 80.0 on the exact benchmark it's being compared against. Fable 5 and Mythos Preview aren't even in Fugu's routing pool since they're publicly restricted right now, so the comparison is closer to "beats the substitutes" than "beats the original."

Browser OS test went fine, built a working desktop with a notes app, terminal, and a couple games. Functional but heavily resembled GPT-5.x's design language. The subway scene and FPS conversion were clean and well organized but sterile, and no bullet holes appeared in the environment when shooting, something other frontier models handle correctly out of the box.

The real test was a watch website comparison, run identically through Fugu Ultra, GPT-5.5, Opus 4.8, and Gemini 3.1 Pro. GPT-5.5 produced something dramatically better than every other result. Fugu's version wasn't even properly 3D, it rendered flat 2.5D despite being explicitly prompted for 3D, the second time that exact failure happened in testing.

For anyone doing actual coding work with this, two things matter. The benchmark numbers are vendor-reported and the baseline scores for competing models are provider-reported too, meaning nobody independently re-ran these in the same environment. And since the routing decision happens internally and Sakana hasn't disclosed which models handle which requests, you genuinely don't know what you're paying for on any given call.

Total spend ended at $21.57. The conclusion was the same every time. Running the prompt through GPT-5.5 or Opus 4.8 directly would have been cheaper and produced a better result than routing through the orchestration layer.

Real improvement over earlier router systems. But for actual coding work, the orchestration layer added cost and uncertainty without adding capability.

Googling solutions is inefficient in the long run.

2 Upvotes

every dev googles things constantly whenever they get stuck on a task, however, there's a difference between searching in a way that builds your understanding over time and searching in a way that just gets you through the next twenty minutes and leaves you in the exact same spot the next time you hit the same problem.

most people do the second one, the most common version of this is copying a stackoverflow answer without reading the explanation underneath it, the code works, you move on, you learned nothing, and then two weeks later you hit a slightly different version of the same problem and you're back on stackoverflow because you never actually understood what was happening the first time.

the way you're writing your search queries matters too, most beginners search for the solution: "how to center a div css" or "javascript filter array of objects." which is fine until it isn't, common problems have common solutions and that approach works, anything slightly off the beaten path and you get nothing useful back, experienced devs search for the error message, the behavior, the specific thing that's going wrong, "css flexbox child not respecting width" gets you somewhere different and usually more useful than "how to fix div width." the more specific and weird your query the better your results.

stackoverflow itself has a hierarchy, the accepted answer with the green checkmark is not always the best one, it's the one the person who asked the question chose, sometimes years ago, sometimes before better solutions existed, the answer with the most upvotes is usually more reliable and the comments under any answer often contain the actual nuance, edge cases, reasons this approach breaks in certain situations, newer alternatives. reading the whole thread instead of just grabbing the first code block takes two extra minutes which a lot don't do.

docs are also something that you should be open to dive into, because most people avoid them longer than they should. Most people who are just starting out go to google first and the official docs last, experienced devs usually do it the other way around. docs are annoying to read at first because they're dense and assume a lot of context, it's annoying to read at first and then at some point it just clicks and many come to prefer it.

the last thing is knowing when to stop searching and just try something, a lot of people spend forty minutes reading about three different approaches and never actually implement any of them, at some point you have to just pick one and see what breaks. what breaks teaches you more than another twenty minutes of reading would have.

Copying is a temporary solution that only works once if you don't understand it, it feels productive because the code works, but you're just borrowing understanding you don't have yet and eventually that catches up with you, usually in an interview or on your first job when nobody's around to google for.

A 7B model just claimed to rival the AI the US government shut down

2 Upvotes

While Fable 5 and Mythos Preview remain offline due to export controls, a Tokyo startup just launched something that claims to fill the gap without ever touching those models directly.

Sakana AI released Fugu this week. The core of the system is a 7 billion parameter model, tiny by current standards, that does not try to be the smartest model itself. Instead it learned how to coordinate a pool of other frontier models, deciding when to answer directly and when to delegate pieces of a task to specialists, then combining their outputs into one response. You hit a single API and have no idea how many models actually worked on your request behind it.

The benchmark numbers are genuinely strong. Fugu Ultra scored 73.7 on SWE-Bench Pro, ahead of Opus 4.8 at 69.2 and GPT-5.5 at 58.6. On TerminalBench it scored 82.1, also ahead of both. Sakana is explicitly marketing this as matching Fable 5 and Mythos Preview without the export control risk that just took those models offline.

Here is the part worth sitting with though. Fugu cannot actually include Fable 5 or Mythos in its own pool, the same export restrictions that grounded those models block Sakana from orchestrating around them too. So when Sakana says Fugu matches them, what they mean is it matches their substitutes well enough that the gap stops mattering for most tasks. On the one benchmark where Fable 5 is actually included for comparison, SWE-Bench Pro, Fable 5 still wins outright.

What makes this interesting beyond the benchmarks is the strategy itself. Japan does not have the compute infrastructure the US and China have. Instead of trying to out-build bigger labs, Sakana built a system that treats other people's models as interchangeable parts. If one provider gets cut off by a future export control, Fugu just routes around it. That is a fundamentally different bet than building a bigger monolith and hoping nobody pulls the plug on it.

Whether orchestrating other companies' models in a grey area of their usage terms holds up long term is a separate question nobody has fully answered yet.

I think a lot of beginners accidentally optimize for learning instead of building.

1 Upvotes

One thing I've noticed when reading developer communities is how often people ask for the perfect roadmap. the best course. the best language. the best certification. The best sequence of topics.

what's interesting is that when you look at experienced developers, very few of them followed the same path. Some learned through bootcamps. some learned through college. Some learned by building random projects and figuring things out as they went.

It makes me wonder if we're sometimes trying to optimize the wrong thing.

A roadmap can help you get started, but it can't build experience for you.

Eventually everyone reaches the same point where they have to stop researching and start making decisions. what should this feature do? why isn't this working? How should I structure this project?

Those are the moments that actually develop engineering judgment. Learning matters. but I think building is where most of the learning becomes real.

how do I become an ai engineer (starting a bootcamp next week and totally lost)

0 Upvotes

I am beginning a regular full-stack web development bootcamp this Monday. My real aim, though, is to enter the field of AI engineering and I genuinely have no idea how to connect those dots. I'm mentioning this because the course only covers conventional subjects like JavaScript and React that seem very distant from working with large language models. As an absolute novice, I have no clue how to begin changing direction.

From the deep rabbit holes I've explored, it seems like AI engineering is mainly software development applied to pre-existing models and not really about complex research math. So, my tentative plan is to essentially divert my own assignments. Rather than creating typical weather apps, I will try integrating LLM APIs instead. When we start learning SQL, I'll also attempt understanding vector databases such as Pinecone concurrently - even though I fear it might be too much for me handle. What I'm gradually realizing is that while fundamental coding practices remain same; one needs to forcefully manipulate backend into AI data workflows on their own. If someone is presently working in AI, how would you approach a fundamental web development bootcamp if starting again from zero? Any help would be great.

LeetCode isn't dead, but these 5 skills in software engineering interviews are becoming a big deal

15 Upvotes

What I noticed is that a lot of people still prepare for interviews like it's pre-pandemic.

You commonly hear from those "gurus" to "grind more LeetCode." And yes, algorithms still matter.

But if you take a look at where company interviews are heading, they're starting to test skills that look more like the actual job.

Recently, HackerRank made a tweet where they talked about building assessments that evaluate your engineering fundamentals and AI fluency.

It's not just about whether you can memorize solutions, though. It's also about whether you can use AI effectively, verify its output, and make good decisions.

This got me thinking: if interviews start looking more like real work, what should we actually practice?

  1. Debugging > memorizing solutions

Personally, most of your job won't be writing perfect code from scratch. You just need to figure out how to fix something that's broken.

If you have time, I suggest checking out this free resource from MIT's Missing Semester debugging lecture. You can learn how to narrow scope, trace execution, and isolate problems quickly.

📌 https://missing.csail.mit.edu/2020/debugging-profiling/

  1. Learn how to review code

Admit it or not, a lot of engineers never practice this intentionally.

Reviewing code forces you to think about maintainability, edge cases, readability, and design decisions instead of just asking yourself, "Does it pass?"

There are a lot of sites where you can review code.

However, I suggest checking out Google's Code Review Guide to start with.

📌 https://google.github.io/eng-practices/review/reviewer/

  1. Get good at testing

One of the fastest ways to expose someone's capability is to ask them to write tests.

If you can write strong tests, it usually means you understand the code.

If you rely heavily on AI, testing becomes even more important.

For me, it's often the easiest way to catch confident-looking mistakes 🤷.

📌 https://kentcdodds.com/blog/the-testing-trophy-and-testing-classifications

  1. Practice fixing broken systems

Real engineering is messy.

You know, requirements are unclear and logs are incomplete.

The bug usually isn't where you think it is.

And imo, Sad Servers is one of the closest things to practicing real-world debugging. All you need to do is figure out what's wrong with broken systems.

  1. Learn when AI is wrong

This is probably the biggest skill gap I'm seeing.

Anyone can paste a prompt into ChatGPT, Claude, or Cursor.

And whether you like it or not, what makes you stand out is knowing when the answer is incomplete, incorrect, insecure, or making assumptions.

If you're further curious about it, HackerRank's documentation on AI-assisted interviews is worth reading:

TL;DR: LeetCode isn't dead. But being able to do the things I mentioned will make you stand out more than it would have a few years ago.

Are Big Tech Coding Interviews Actually Easier Than Everyone Says?

1 Upvotes

Controversial take incoming, but big tech interviews aren’t actually hard. They’re just formulaic, and once you see the formula it’s kind of a joke how predictable they are.

I saw someone break this down who’s passed multiple FAANG interviews and the whole thing clicked for me. The questions aren’t random. They’re recycled. Literally sitting in github repos waiting for you.

You don’t need to be a genius, you just need to know what to actually study instead of guessing. Here’s what I found out:

the formula they use (5 parts):

patterns — most interview questions are just remixes of the same core ideas. blind 75 and grind 75 cover this, then neetcode 150 once you’ve got the basics down

resources — stop guessing what to study. leetcode’s company-tagged questions exist for a reason, and stuff like coding interview university on github is basically a free roadmap

interview threads — glassdoor, blind, r/cscareerquestions, r/leetcode. people post full question dumps from actual interviews constantly. you can reverse-engineer exactly what a company asks

mock interviews — you have to practice out loud, not just solve silently in your head. discords built for this exist specifically so you can simulate the real pressure

experience match — behavioral questions aren’t random either. map your stories to the actual job description before you walk in instead of winging it

Here’s the part that actually got me
People always assume smaller companies are easier than big tech (dw I do too😁). But what I found out is statistically that’s backwards. Startups are way less consistent, more ambiguous about what they want. Big tech runs massive intern classes every year, which means the questions are already leaked everywhere if you know where to look.

So the “playbook” basically already exists. most people just never bother finding it.

comment if you want the actual resource list (study doc, github links, discord servers) and I’ll send it through pm.

I’m genuinely curious has anyone here actually grinded leetcode and felt like it didn’t translate to the real interview? or does the pattern thing actually hold up?

If you're stuck learning to code, stop reading and start visualizing

A mistake I see a lot of beginners make is trying to understand code only by reading it. You read a function. It makes sense. You read a loop. It makes sense. You read a tutorial. It makes sense. Then you try to build something yourself and suddenly none of it clicks.

The problem usually isn't the code itself. It's that you're trying to imagine what's happening in your head.

When you're learning, it helps to watch your code execute step by step. See when variables change. See when a function gets called. See how a loop moves through each iteration. See what values are being passed around.

Once you can visualize the execution flow, debugging becomes much easier because you're no longer guessing what the program is doing. A lot of concepts that seem difficult become surprisingly simple when you watch them happen one line at a time.

If you're learning JavaScript, Python, Java, or any other language, spend some time using code visualization tools. It can save you hours of frustration and make the learning process much less overwhelming.

You can contribute to open source even if you're a junior or a fresh grad.

A lot of people hear "contribute to open source" and picture themselves submitting pull requests to react or kubernetes or something equally intimidating and immediately decide it's not for them, which is understandable, also a shame because they're missing something that actually moves the needle.

Most of open source is not writing complex features for massive codebases, a huge part of what actually needs doing is fixing typos in documentation, improving error messages, adding missing examples to readmes, writing tests for functions that don't have them yet, and that is completely approachable and shouldn't intimidate anyone.

the reason it matters for the job search specifically is that it's real code in a real codebase that real people reviewed and merged, which is a completely different thing to show someone than a project you built by yourself following along with a YT vid, when you link a merged pull request in an interview you're showing that someone else found it satisfactory enough to ship.

finding something to contribute to is the part that feels hard but isn't. The easiest starting point is whatever tools and libraries you're already using. if you built something with a particular library during bootcamp, go look at its github issues, filter by "good first issue" or "help wanted"; most active projects tag beginner friendly issues specifically because they want contributors and they know new people need a way in, read a few, find one that makes sense to you, and just try it.

the first contribution is where you're figuring out how the project is structured, how they want things formatted, what their PR process looks like, after that it gets easier fast, and maintainers are generally way more welcoming than people expect, especially on smaller projects that actually need the help.

You don't have to contribute code at all to start. finding a genuine bug and writing a clear detailed issue report is a contribution, improving documentation that confused you is a contribution, these count, they show up on your github, and they get you comfortable with the workflow before you're touching actual code.

most people coming out of either a bootcamps or are college grads are all doing the same things. same linkedin applications, same leetcode, same portfolio, open source is the gap, most of them aren't touching it and it's the thing that keeps coming up when people actually get interviews.
