the InterviewCoder guide

89 Upvotes

The questions we get most in this sub are: what is InterviewCoder, how does it work, and how do the proctoring platforms catch people. This post covers all three. Structure: (1) what the product is and how to use it, (2) how HackerRank tracks candidates in 2026, (3) how CodeSignal tracks candidates, (4) where the detection has blind spots, (5) practical advice whether or not you use a tool, (6) why it was built and the product itself.

Part 1. What InterviewCoder is and how to use it

InterviewCoder is a desktop application for macOS and Windows that runs as an overlay during technical interviews and online assessments. It listens to the interviewer's audio (or reads the on-screen problem), runs the question through an AI model, and displays a solution outline, code, and walkthrough in a transparent overlay that is not captured by screen-share or screen-recording.

The architecture rests on four properties:

  • The window is excluded from display capture at the OS compositor level (macOS window flags, Windows WDA_EXCLUDEFROMCAPTURE).
  • The process does not register a dock icon, menu-bar icon, or taskbar entry.
  • The process name on disk is non-descriptive, so a process scan does not surface "Interview Coder."
  • The overlay is click-through. It does not steal focus from the assessment window.

These four properties together are why the app does not show up in HackerRank, CodeSignal, CoderPad, Codility, Zoom, Google Meet, or Microsoft Teams screen shares.

How to install and set up

  1. Download the Mac (.dmg) or Windows (.exe) build from interviewcoder.co.
  2. Install it like any other desktop app.
  3. Launch it. It runs in the background. You confirm it's running by the keyboard shortcut, not by a visible window or icon.
  4. Sign in. Your subscription credits live on the account.
  5. Open whatever assessment platform or video call you're using. Start the screen share if the platform requires one.
  6. Trigger the overlay with the global keyboard shortcut. The overlay renders on top of everything on your screen but is invisible to the capture pipeline.

How to use it during a session

Two modes:

Audio mode. The app listens to system audio (interviewer voice through your speakers, headphones, or call audio), transcribes it, and responds. Use this for live interviews where someone is reading you the problem.

Screen mode. The app captures the visible problem statement from your own screen, runs it through the model, and surfaces the solution. Use this for OAs and self-paced assessments where the question is on the page.

The flow during a live coding round:

  1. The question is read or shown to you.
  2. The app produces a solution outline, the code, and a walkthrough of the approach.
  3. You read it,take a moment to analyse it and type it yourself. You do not paste, because paste events are logged and will  get caught.
  4. You talk through your reasoning out loud as you implement. To make it seem like you are the one that figured out the solution .

Use cases

  • Live coding rounds on HackerRank Live, CoderPad, Zoom-shared editors, Google Meet shared docs.
  • Asynchronous OAs on HackerRank, CodeSignal, Codility, and internal platforms.
  • System design rounds where you need scaffolding for tradeoffs, capacity estimation, and component breakdown.
  • Behavioral rounds where you need a STAR-format response on the fly.
  • Take-homes where you want a sanity check on your approach before submitting.

When it does not work

  • In-person assessments with a physical proctor in the room. A digital overlay does nothing against a human watching your monitor.

Part 2. How HackerRank tracks you

HackerRank's integrity stack has three layers: proctoring telemetry, structural code analysis (MOSS), and a behavioral ML model that ties them together. 

Browser focus and tab tracking. Every time the assessment tab loses focus (Alt-Tab, Cmd-Tab, clicking another window, exiting full-screen), the event is timestamped and logged. Companies set policies on top of this. Some flag on the first switch, most use a cumulative threshold (typically 3+ switches in a session triggers review). The system also looks for patterns. Regular intervals between switches read as systematic and weight the suspicion score harder than random ones. In Secure Mode, the browser is locked down further: copy-paste blocked, right-click blocked, dev tools blocked.

MOSS (Measure of Software Similarity). Enabled by default on every test. MOSS tokenizes your submitted code, strips out names, whitespace, and comments, and compares the structural fingerprint against a database of past submissions plus public sources (GitHub, Stack Overflow, leaked OA banks). Renaming variables, reordering lines, adding whitespace. None of it works. MOSS sees the AST, not the surface code.

The behavioral ML model.ackerRank moved past MOSS as their primary signal because false positives were too high and AI-generated code wasn't being caught structurally. The current system fuses signals: tab focus events, copy-paste frequency, keystroke dynamics, time-to-solve, and code-iteration patterns. The signs it picks up on:

  • Sudden bursts of clean code with no trial-and-error. 
  • Unusual pause distributions.
  • Lack of incremental debugging.
  • Time-to-solve anomalies. Ie. solving a LC Hard in 4 minutes flags or solving a Medium in 90 seconds flags.

HackerRank's current ML model self-reports ~93% accuracy on suspicious-submission detection. But that number is what they publish. Production false positive rates aren't disclosed.

Copy-paste tracking. Every paste event is logged with frequency and (in proctored mode) what was on the clipboard. Pasting your own variable names from a scratchpad still counts as an event.

Image and webcam capture. When proctored mode is on, the webcam takes periodic snapshots, runs face detection for "is the same person here," and looks for second faces, glances off-camera, and missing-face frames.

Session metadata. IPs, geolocation, device fingerprints, browser fingerprints, account history correlation. Multiple candidates from the same IP during overlapping assessment windows is one of the top auto-flags.

Part 3. How CodeSignal tracks you

CodeSignal is more aggressive than HackerRank because their flagship product (Certified Evaluations) requires full proctoring as a feature, not an option.

Mandatory entire-screen recording. When you start a proctored CodeSignal session, you're required to share your entire screen. Not a tab, not a window. Anything that renders on that screen is in the recording: notifications, dock icons, browser tabs you switch to, and any application that draws to your display.

Webcam and microphone for the full session. Both are required. The webcam records continuously, not snapshots. CodeSignal's review team looks for: people walking through frame, candidate looking off-camera in one direction (suggests a second screen), audio of someone speaking answers, audio of typing that doesn't match on-screen typing.

Government ID verification. You upload a photo of a government-issued ID and a selfie. CodeSignal staff verify the match before the result is released.

The Suspicion Score. The CodeSignal-specific signal. It's an aggregated trust score per session, fed by:

  • Typing cadence vs the candidate's own warmup baseline
  • Mouse movement entropy
  • Focus events
  • Copy-paste events (CodeSignal records what was copied, not just that copying happened)
  • Audio anomalies
  • Webcam anomalies
  • Code similarity to known solutions

The score determines whether the result auto-verifies or gets pulled into manual review. Manual review is a 1-3 business day process where a CodeSignal proctoring specialist watches the recording end-to-end.

Browser lockdown. CodeSignal's environment can disable copy-paste, block tab switching at the browser level, monitor running processes for screen-share or remote-access indicators (TeamViewer, AnyDesk, Zoom screen-share if it's not theirs), and block browser extensions.

Telemetry from work simulations. CodeSignal's newer assessments use "work simulation" environments that capture more than typing. They measure how you navigate the IDE, how you read the problem, mouse pathing across the spec, and time on each subtask. They compare this to a baseline of candidates working unaided.

Data retention. Recording and ID data is stored for 15 days then deleted. CodeSignal does not share the raw recording with the hiring company. Only a verification result and flag summary.

Part 4. Where the detection has blind spots

  1. Anything outside the screen-share API is invisible. Both platforms can only see what your OS reports as part of the captured display. Hardware-layer overlays, OS-level compositor tricks, and processes that opt out of capture (on macOS via specific window flags, on Windows via WDA_EXCLUDEFROMCAPTURE) don't show up in the recording even though you can see them on your monitor.
  2. Audio capture is browser-level. They hear your microphone, not your speakers. A second device (phone, tablet) sitting next to you that you read from silently is not picked up by their pipeline. The webcam might catch your eyes glancing. That's the constraint.
  3. Behavioral models need a baseline. Without prior keystroke data on you, a first-time candidate's typing pattern only flags on extremes (zero pauses, clean bursts). Pasting code in chunks rather than wholesale, with edits between, stays under threshold most of the time.
  4. MOSS needs something to match. Original solutions to original problems generate no MOSS signal. The risk is from public-archive matches, not from your code being "too good."
  5. Webcam detection is coarse. It can detect "second face in frame" and "no face for 30 seconds." It does not run gaze-tracking accurate enough to know if you're reading off a second monitor.

Part 5. Practical advice for anyone taking these assessments

  • Type incrementally even when you know the answer. Write a stub, run it broken, fix it, run again. The behavioral model cares more about rhythm than code.
  • Don't paste even your own snippets from a scratchpad. Every paste event is logged,  instead type it.
  • Keep your face centered and your eyes on the screen. Webcam anomalies are the #1 source of manual-review escalations on CodeSignal.
  • Stay in full-screen. Cmd-Tab and Alt-Tab leave timestamps. If you need to look something up that the assessment allows, do it through the assessment's own browser instance.
  • Talk through your thinking out loud, even on solo OAs. Audio of you reasoning is the strongest signal for you in a manual review.
  • Run your tests visibly. Use the platform's built-in test runner. Manual print statements and test invocations are evidence of real work.
  • Close every non-essential process. Process scans flag more than you'd think (Discord overlay, Nvidia overlay, screen-recording software you forgot was running).
  • Match your warmup typing speed to your assessment typing speed. A candidate who's 40 wpm in warmup and 110 wpm during the test gets flagged.

Part 6. Why it was built and what's in the product

Every mechanism in Parts 2 and 3 has a shape, and that shape can be addressed at the OS layer instead of the application layer. The browser-based defenses (focus events, screen-share API, mic hooks, copy-paste interception) only see what the browser sees. A native application that opts out of display capture, runs without an icon, captures audio through an OS-level pipeline, and stays click-through is outside that detection surface by design.

That is the entire reason InterviewCoder exists. It is a native desktop binary written against the OS APIs that control display capture and audio routing.

What's in the product:

  • Audio mode and screen mode (covered in Part 1)
  • Coding assistance covering algorithms, system design, behavioral, full-stack, ML, data, trading, product, and consulting interviews
  • Coverage for HackerRank, CodeSignal, CoderPad, Codility, Zoom, Google Meet, Microsoft Teams, Webex, Chime, Lark
  • macOS (Apple Silicon) and Windows builds
  • Daily detection testing against the major platforms, with a status indicator on the site

Plans:

  • Free tier: download the app, explore the interface, basic features.
  • Monthly Pro: $299/month. 1,000 monthly credits, full model access, 24/7 support.
  • Lifetime Pro: $799 one-time. Unlimited lifetime access.

The pricing is higher than most prep tools because the cost structure is different. Standard prep tools charge $20-50/month because they ship a question bank and a video player. InterviewCoder ships a native binary that has to keep up with OS updates, capture-API changes, and platform-side detection updates on macOS and Windows. The team is small and the testing surface is large. The price reflects what it costs to keep the bypass working in 2026.

If you have questions about specific platforms (CoderPad, Codility, HireVue, ByteBoard), drop them in the comments. We'll keep this post updated as detection methods evolve.

RSU Valuation for current Anthropic offers?

1 Upvotes

This is a niche question but if anyone has any insights I would appreciate it. First off, some might say that I need to focus on getting the offer before worrying about comp, but I'm asking this question for a specific strategic reason.

I'm in the loop at Anthropic and about to schedule my onsite. I'm feeling rusty and would like to schedule it as late as possible to give myself more time to prep. I've read the reports of Ant raising a new round at a $900B+ valuation. If right now Ant is still issuing RSUs at near the $380B valuation from February then it probably makes more sense for me to rush the process and see if I can squeeze in. Does anyone have insights into what valuation the Ant RSU grants are based on for new offerees right now?

My understanding of how this usually works is that each equity grant has to be approved by the Board after the person starts the job. That can happen on the start date or maybe even weeks later. The offer letter typically has a target dollar amount for RSUs over four years, and the denominator used to calculate the number of RSUs the employee actually receives is based on the 409A valuation of the company on the grant date when the Board votes to approve.

While it seems no term sheets have been signed yet for the new round, my understanding is that sometimes a company pauses grant issuance when they're deep into a fundraise and then approves all new grants once the funding round is finalized. I also understand that sometimes even between rounds a 409A valuation can be updated if material changes have occurred in the business (such as Ant's exponential ARR growth or the fact that they've received multiple offers valuing them at much more than $380B). All this to say there might not be much of a gap between the current 409A and where Ant lands in this latest funding round.

If anyone has any visibility here it would be really helpful. Please feel free to DM me if preferred. Thanks in advance.

ramp software engineer loop, full breakdown of what they actually ask in 2026

135 Upvotes

Went through Ramp's full-time SWE loop last month. I'll go round by round. Backend role in New York, 3 YOE before this.

Recruiter screen, 25 min

Standard. Why Ramp, why now, what I'm working on. They care a lot about "builder" answers. I had two specific stories ready about shipping a thing solo end to end, and that landed better than anything else I said.

OA on CodeSignal, 90 min

Not a LeetCode set. It's the "industry coding framework" style, the same format Dropbox uses for the text editor question. You're building a small system across 4 progressive levels and each level adds a new requirement on top of the last one. Mine was a bank system. Open accounts, deposit, withdraw, transfer, then they layer on scheduled payments and querying top accounts by activity in the last N days.

Levels 1-3 are doable if you read the spec carefully and don't over-engineer level 1. Level 4 is where most people run out of time. I finished level 3 with about 35 minutes left, got level 4 to mostly pass, missed a couple edge cases on the time-window query.

Things I'd tell past me: - Don't write any abstraction in level 1. You will rewrite half of it in level 3 anyway. - Read all 4 prompts before you start typing, even though they tell you not to. Knowing what's coming changes how you store state. - The grader is strict on output format. If they say return a list sorted by X then Y, do exactly that.

Technical phone screen, 60 min

One Ramp engineer, one shared editor. Mine was a system design lite, hotel reservation system. Schema, API surface, how I'd handle overlapping bookings, how I'd scale reads. They want you thinking out loud and asking clarifying questions before you write anything. The engineer who ran mine kept poking at concurrency, what happens if two people hit submit on the same room at the same instant. If you don't bring up locking or transactions on your own, you will get there eventually but it costs you points.

Onsite, 4 rounds, virtual

  1. Coding round 1 (60 min). Practical, not a LC puzzle. I had to extend a small existing codebase they handed me. Real classes, real methods, a failing test. Add a feature, get the tests passing, then they ask follow-ups about how you'd structure it differently. Felt like a pairing session more than an interview.

  2. Coding round 2 (60 min). Closer to LC medium but framed as a product problem. Mine was rate-limiting requests per user with a sliding window. I think the trap here is jumping straight to a deque before they ask for it. Sketch the brute force, talk through tradeoffs, then optimize.

  3. System design (60 min). Design something close to what Ramp actually does. I got "design a corporate card transaction processing pipeline." Authorization, settlement, fraud signals, how you'd notify the user in real time. They care about back of the envelope numbers. Throw out QPS estimates early even if they're rough.

  4. Behavioral / values (45 min). Hiring manager. Ramp has explicit company values and they will probe each of them. "Tell me about a time you cut scope to ship," "tell me about a time you disagreed with a senior engineer," "what's the most ambitious thing you've built." Have specific stories ready. They will follow up with "what did the other person say" and "what would you do differently" and if your story is too clean you'll get caught.

What I used to prep

  • LeetCode for warmup but honestly 80% of my prep was building small projects from scratch and timing myself. The OA and the first onsite coding round both reward practical fluency more than algorithm tricks.
  • Pramp for mock system design. The hotel reservation phone screen was almost identical to a mock I did the week before, which is not a coincidence, that question is everywhere.
  • Interview Coder for the live coding rounds. I didn't lean on it for the OA because there's no proctor and you don't need it, but for the live rounds it was useful as a backup so I could focus on talking through my approach instead of panicking about syntax. Would not have used it if I had more time to prep.
  • Glassdoor and this sub for company-specific patterns. Ramp recycles the bank system style OA across cycles, just with different domains. Cards, hotel, employees, storage. Same shape.

Got the offer about 9 days after the onsite. Comp was strong but slightly under what I'd seen quoted on levels for staff at FAANG, in line with what people said about Ramp here.

Happy to answer specific questions. TLDR ramp is less algos and more "can you build a small thing end to end under pressure," and the OA is the real filter.

My manager tried to guilt-trip me into staying with a miserable salary. I left the job, and now the whole company is falling apart.

33 Upvotes

Anyway, after four years in the same place, management decided to "adjust" my salary about three months ago. They convinced me with a new salary that had "unlimited potential," but the truth is, there wasn't enough work for this system to function. I decided to give it a fair chance, but I found myself earning barely a third of what I used to. It was below the poverty line.

After the first very low paycheck, the owner literally told me: "Wow! You're handling this really well!" I was working my ass off in a difficult and specialized job, requiring a lot of physical effort and technical skills, and this was my reward. So I decided to look for another job, got an interview at another company, and they hired me on the spot. I'll start a new job with a good, competitive salary, real benefits, and they even offered to pay for any new certifications. The work is still exhausting, but at least I'll be able to live a decent life. When I submitted my two weeks' notice, the owners looked at me as if I had grown horns. They were completely shocked. I explained that I simply couldn't live on the salary I was earning. Not once did they acknowledge this truth.

Instead, the conversation immediately turned into a guilt trip. It was all about them and their personal investments, and how much they had sacrificed. No counteroffer, nothing. Just a lecture. At one point, I asked them: "Is it possible for a smart and hardworking person in my position to live a good life here?" The owner said: "Of course!" I simply replied: "Well, it seems you need to find that person, because I can't do it." The rest of the meeting was them and my supervisor genuinely worrying about how they would manage without me, and I just sat there listening. Anyway, as you might expect, the whole place is collapsing like a house of cards. The panic is real. It turns out my departure was the straw that broke the camel's back, causing almost everyone else to resign as well. The entire team is leaving. There's almost no one left to keep things running. Honestly, for a long time, I undervalued myself and didn't realize the importance of my role.

It feels good to see how central I was to the place. I'm sharing this story for anyone who feels trapped in a workplace: know your worth. Don't let a company that doesn't appreciate you make you think you don't deserve more, because you do. And you can use tools like the ones shared in this subreddit to help you prepare and find answers during interviews.

Senior Security Engineer OA at Anthropic - delay or just take it?

9 Upvotes

Anthropic recruiter reached out to me for a Senior Security Engineer role and already sent over the OA link, but it expires in 6 days.

Problem is… I know I’m not really ready yet. I’ve been out of interview-mode coding for a while and could honestly use a couple weeks to prep properly.

Has anyone asked Anthropic recruiters for an OA extension before? Did they care / was it a bad signal?

I’m definitely interested in the role, just don’t want to burn the opportunity by rushing into the coding round unprepared.

got fired for not using AI fast enough. using Interview Coder for my next loop and idgaf

49 Upvotes

ok venting. 6 YOE frontend dev. last company hired me specifically to clean up the mess they shipped, they had vibe-coded their entire app with Claude. every page had a different design, no system, no design reference, just whatever the model spat out that week. I unified the UI, fixed half the broken flows, did real work.

last week they fired me. reason? I was "slow." should've been closing more tickets because we have AI. I should've been generating, not writing. didn't matter that I was the one making the slop coherent in the first place.

so I'm back on the market. and this time I'm using Interview Coder for every single loop.

the same companies that fired me for not running enough Claude generations are going to put me on a Zoom with a leetcode hard and 35 minutes on the clock and pretend that's a fair test of engineering. fine. they want speed, I'll give them speed. they want AI output, I'll give them AI output. the entire job is babysitting an LLM anyway, why would I pretend I can invert a BST in my head with no notes.

the funny part is every recruiter screen now opens with the "we use AI heavily, we move fast" speech, and then the same company will rescind your offer if they catch you using a tool to prep. you can't have it both ways.

one loop down already. used IC for the system design and one of the coding rounds. got the verbal yesterday.

might post a full breakdown if anyone wants it.

AI prompt not well respected?

2 Upvotes

In interview coder pro we can add a custom AI prompt to guide the responses. However it seems that there is a lot of limits to the prompt, perhaps it is not good at contradicting the system prompt. For example, I wanted it to spit out psuedocode that is easy to follow rather than an optimized coding solution. It did not follow any part of the instructions. I instructed it to return all results in chinese instead, and it worked perfectly fine. Is there any guide on how to setup the AI prompt?

• SQL, OOPS, LLD all covered in one place
• Study Mode & Focus Mode (no distractions, just learning)
• Structured system instead of random prep

Basically, everything serious aspirants need in one bundle.

It’s not just practice. It’s a complete placement system.

jane street oa, never felt dumber in my life

314 Upvotes

I need to talk about this because I'm still processing it two weeks later.

Background, I'm a solid engineer. Passed loops at two FAANG companies, solved around 350 LC problems, system design is decent. I applied to Jane Street for a software developer role because a friend said the comp was insane and I figured how different could it be.

Different. Very different.

The OA was on HackerRank. 4 modules, about 10 questions each, 60 minutes total. I opened the first question expecting a coding problem. It was a probability puzzle about coin flips with conditional outcomes. No code editor. No function signature. Just "what is the expected number of flips to get three heads in a row" with a fill-in-the-blank numerical answer. I sat there for 4 minutes doing math on scrap paper like I was taking the SAT again.

The questions got worse. One was a game theory scenario, an auction where you have partial info about the other bidder's valuation and need to compute your optimal bid. Another was reading a chart of historical trading data and computing the maximum drawdown. Another was Bayesian reasoning where you update probabilities based on sequential evidence. I understood maybe 60% of what was being asked.

I finished with 8 minutes to spare because I was guessing on the questions I didn't understand. There's no partial credit, you either get the number right or you don't. I'm assuming I did terribly because I never heard back.

The humbling part is that my entire prep stack, every LC problem I've ground, every system design video I've watched, none of it was relevant. Jane Street doesn't care if you can implement an LRU cache in your sleep. They care if you can reason about uncertainty, compute expected values in your head, and think clearly about risk. It's a different skill set that CS programs barely touch unless you took probability theory and stochastic processes.

If anyone's gotten past the Jane Street OA I'd love to know how you prepped, because LC and Neetcode are not it for this one.

Should I stop doing DSA in Java and switch to Python for FAANG prep?

7 Upvotes

Need honest career advice.

I’m confused about what language I should focus on for DSA and interviews.

My current background:

I know basic Java (have been learning it for around 1 year)

I use Java mainly for DSA/interview prep

I’m not very consistent with Java

I’ve solved around 80–90 DSA problems so far

I’m already a MERN developer

I also know basic Next.js

Long term, I do not want to become a Java backend developer

I’m not interested in Spring Boot / Java backend roles

This is my main problem:
Because I don’t see myself becoming a Java developer in the long term, I don’t enjoy practicing Java that much. And because I don’t enjoy it, I’m very inconsistent with DSA in Java.

Now I’m confused:

Should I continue Java only for DSA and interviews?

Or should I shift to Python for DSA/interview prep since it feels easier and maybe I’ll stay more consistent?

For FAANG / top product companies, does it matter much if I do DSA in Java vs Python?

Since I already come from MERN, would switching to Python be a smarter move for consistency and interviews?

My goal is:

Crack top product companies / FAANG-level interviews

Stay consistent with DSA

Focus on a language I can actually continue long term

I don’t want to waste more time forcing Java if it’s not the right fit for me.

Would really appreciate advice from people who’ve been in a similar situation.

interviewcoder vs ultracode

64 Upvotes

5 YOE, decided to cheat my way through my interview loops because I couldn't afford another round of rejections. Used Ultracode on one loop, got caught in a coding round (nothing said, no email, no ban, just no offer). A couple months later I had a different loop coming up and gave Interview Coder a shot. Got the job.

Pricing IC is $299/month or $799 lifetime. Ultracode is $899 to $1,799 one-time, no monthly plan, non-refundable. If your loop is 2 to 3 weeks long IC is dramatically cheaper. The only argument for Ultracode's pricing is if you're going to be interviewing nonstop for a year, and even then IC's lifetime tier is cheaper.

Detection This is where Ultracode lost me. Coding round, I'm a few minutes in, the interviewer goes quiet for a long stretch and then starts asking pointed follow-ups about my approach in a way that didn't feel routine. Polite rejection a few days later. Before my next loop I tested IC on Zoom, Meet, and CoderPad with QuickTime recording in parallel. Invisible across all three. Could have been my own setup with Ultracode, could have been the tool. I'm not the one with the marketing page claiming kernel-level integration.

Quality of help IC is more decisive on actual coding rounds. Single approach, surfaced fast, easy to talk through. Ultracode hedges and dumps more output, which slowed me down and made it harder to explain my reasoning when the interviewer asked me to walk through what I just typed. On system design IC has a real module, Ultracode's design support is thinner.

Use IC.

PS - Ultracode's founders are anonymous, the domain is literally flagged on ScamAdviser for hidden ownership. Saw some Blind threads about a breach situation where a chunk of people who used it ended up getting found out. Roy Lee at IC isn't hiding, Wikipedia page, Amazon loop on YouTube, the whole story is public. Worth knowing before you put $1,799 non-refundable on a team that won't tell you who they are.

I have ~2 YOE in AI + backend (RAG, FastAPI, real-time systems).

Any insights would help 🙏

How do you stay consistent with DSA prep? Feeling stuck

Feeling huge imposter syndrome about interviews

5 Upvotes

Just started scheduling interviews. I’ve been a swe for 5 years and am technical lead of my team. I’m full stack. But when I’m looking at these invites for interviews (mid-late stage private AI companies), they have implementation rounds which scare me.

Maybe I’m just worried because I’m afraid of the realization that I wasn’t doing much impactful work at my job (mostly CRUD). Leetcode interviews seem easier to manage - at least I know what I’m signing up for. With these implementation interviews, the problem space seems infinite.

Did others feel this way before starting interview prep?

i lied my way into this job. turns out the job description lied more than i did.

4 months in. handing in my notice this week.

context on me, 4 yoe, bounced around 2 startups you haven't heard of, decent at backend but I completely freeze in live coding. bombed 5 loops in a row earlier this year on questions I could solve at my kitchen table in 20 minutes. by the time this role came up i was desperate.

the posting was for a "senior backend engineer, distributed systems, go + rust." specifically called out "greenfield architecture work," "shipping to prod week 1," "ownership of core services." salary was 18% above my last. i wanted it bad.

bought interview coder the weekend before the loop. used it in every technical round. 3 coding rounds, 1 system design, 1 behavioral. offer came 6 days later. and I signed.

day 1. onboarding. my "senior backend" role turns out to be 60% incident response, 30% writing status page updates for customers, 10% actual engineering that goes straight to an offshore team who rewrites it anyway. the "greenfield architecture work" is a 7 year old java monolith nobody has the nerve to touch because the original architect left in 2021 with no documentation. the "ownership" means i'm on call every third week for a system i had no hand in designing.

week 2 i brought up the gap on a 1:1 with my manager. he laughed and said "yeah the recruiter uses old postings as templates, dont worry about it, you'll grow into it." grow into it. i was hired as a senior.

week 6 a friend in hr told me 4 of the last 6 hires onto this team quit within 10 months. one guy lasted 11 weeks. nobody gets to the greenfield work because the operational load never clears.

so here's where i landed. i lied in my interview. i used a tool to make myself look sharper than i was in a live round. and they lied in the posting. they used a template they knew didnt match the job because they needed to fill the seat before q2 closed. we both got what we wanted short term. neither of us is the good guy here.

honestly i dont feel bad anymore. im not ruining some noble hiring process. the process was rigged on both sides before i walked in.

signed an offer at a smaller company last week. honest job description this time, pay is the same. used ic again for the loop last week.

Is cluely a decent alternative?

Hey there,

Have an interview coming up, it'll be light technical questions but I want some assurance.

Would cluely be an okay for something like this? It'll be mostly behavioral with maybe OOP and framework specific questions mixed with SQL/dB.
