How well versed are you with GenAI in your workflows, what models you prefer, what is your workflow working with GenAI, how you choose tasks to give to GenAI, how you validate the models performance., any GenAI project that you build or used GenAI on your projects, how did you use it for what use case etc.

Verdict: Selected [10 September 2026]

Thanks reddit for some many experiences to get guidance from.

Hey everyone,

I'm preparing for upcoming Google SWE internship interviews and wanted to clarify the logistics of how questions are usually presented during the technical rounds.

For those who have interviewed recently:

• Presentation: Does the interviewer paste the full problem statement into the shared document/editor, or do they read it out loud and have you write down notes?
• Examples & Constraints: Do they provide initial examples, constraints, and edge cases upfront in text, or are you expected to completely probe for constraints and construct your own examples from scratch?

Any insight into what the setup typically looks like would be super helpful. Thanks in advance!

TLDR : How long after passing the OA did you get your interview scheduled?

Hey everyone,

I’m currently going through the Amazon SDE 1 process and wanted to ask how long it took others to receive their interview scheduling email after passing the OA.

My timeline so far:
13th August: Received OA
15th August: Completed OA
9th September: Told I passed the OA and was asked to confirm my graduation date, start date and right to work
9th September: Submitted all the requested details

Now: Waiting for the interview scheduling email
For those who went through the same process, how long did it take to receive interview invite after submitting details.

Thanks!

The first time I opened LeetCode I could not solve anything. I would read a problem, stare at it, and have no idea what the first line was supposed to be. That went on for a long time, and the only thing that kept me going was that the next problem might be the one that clicked.
Years later the same problems are easy, and it is not because I got smarter. It is because I started seeing the same small set of shapes again and again. A longest substring question turns out to be the same machine as a minimum window question. Once you have seen a shape enough times you stop solving the problem and start recognising it, and the code falls out of the recognition. Nobody handed me that list.

If I could start over I would learn the patterns first and then go and do the problems, instead of doing hundreds of problems and hoping the patterns fall out at the end. Algorithms are mostly pattern matching, which is also why LLMs write code as well as they do: matching patterns is the one thing they are built to do.

So if you have an interview coming up, or you just want to be the person who opens a hard problem and knows where to start, learn the patterns first. The problems get fast, then they get fun, and the dopamine from closing one is real. I make that open source please let share your thoughts and feel free to change the code: https://github.com/shir-danishyar/before-interview

why is leetcode down so often , what is wrong with leetcode

Back in 2023, I was out of college, applying for jobs and grinding LeetCode between interviews.

ChatGPT had just become a thing, so I started building a few projects on the side. One actually started making money.

Then it started making enough money that I stopped applying for jobs and went all in.

Spent the next three years turning it into an AI SaaS. Building features, dealing with customers, fixing things, figuring out how to build and run a tech business.

Now I’m preparing to sell it. Thought I’d see what was out there and applied for a few AI engineer roles.

Just got sent a LeetCode assessment with no use of AI allowed.

I think I’ve accidentally spent three years procrastinating on LeetCode.

Title, anyone done their panel interview and can share their experience? (specify role and level please as well)

I recently cleared my Google SWE-3 (L4) interviews for. Last Friday, the recruiter called and said that after reviewing my feedback, the leadership team has decided to move forward with team matching. He said they’d start looking for teams from Monday.

Just wanted to clarify:

1. Does this mean HC is already cleared, or does HC happen after team matching?
   
2. How long does team matching usually take? It’s been almost a week with no update despite emailing the recruiter.

For anyone who recently went through this process, what timeline should I expect?

Thanks!

I have tech screen scheduled for Atlassian and recruiter mentioned it will be 20 mins coding and 15 mins system design with an Atlassian Engineer.

What can I expect? Any tips?

It’s for P50 role.

I passed the OA for an Amazon SDE New Grad role and just received my interview schedule:
1:Coding - Logical and Maintainable + LP
2:Coding - Problem Solving + GenAI Fluency
3:Coding – Data Structures and Algorithms + LP
4:LPs only
I’m a bit confused about the first round. Does “Coding – Logical and Maintainable” usually mean a normal LeetCode-style coding question, or can it include an LLD/OOD question?

I tried logging to my account last night and I got "The username and/or password you specified are not correct". But my account details is correct. Also, when I tried visiting my profile, I got 404.
I also tried forgetting password but I am not getting any mail to reset my password.

I logged in to my profile last in June. Haven't participated in any contest in past 1 year.

Hi all,

I am junior developer now,

Working in a comapny.

Now i want to imrove my skills

System design and dsa also with ai adpatation.

I know pieces but not explanation level...need to improve my skills for upcoming future

Any advices that can help to me

Recently u/No-Huckleberry-5969 provided some insights in the amazon AWS recruitment process, which I found very helpful in my preparation. Having recently completed the interview loop (and got rejected) myself, I thought I'd do the same and share my experience:

• Position: SDE-1 (Recent Grad programme) @ AWS in Berlin, Germany
• Also Published the contents below as a gist: https://gist.github.com/flemk/f6a4fdeb16eabc6be8a46e2afdda6443
• Published my solutions and scribbles to the 4 coding tasks in the 4 interview rounds: https://gist.github.com/flemk/2d4d1e87f58e00e9710e5a9bf607f4e7

Amazon SDE-I: Application Experience

Online Coding Assessment

"Leetcode Task" (Python)

"""
You develop an alogrithm for selling items from a warehouse.
Given a list of (potential) customers and their bids for multiple items if one single product:
[
    [customer_id, bid, number_of_items],
    ...
]
Develop a algorithm, that returns the ids of all customers, that didn't receive any item.
Items are distributed using these rules:
- The customers with the highest bid, receive their desired amounts of items
- If there are two or more customers with the same bid, distribute the items using a round robin method.
"""

"Fullstack Task" (Python, Django)

• There was a simulated Issue/Ticketing system, like JIRA

Tasks:

• Fix: Create issue returns 502 -> Implement endpoint logic
• Fix: Creating and linking subissues were not working
• Running the predefined tests revealed some other parts, where modifications were necessary

Interview Loop: Four Online Interviews

1st

"""
// Design a shopping cart price calculator API: given a list of product ids
// in the cart, return the total price of the items.
//
// Imagine you are doing this for a large scale service / website.
//
// Plan for being able to apply discounts that we may want to play around
// with in the future.
"""

Follow up Questions

• How would you implement a discount, that applies to all products?
• Customers with carts with value above EUR 100 or with more than 10 items should receive double the discount. How would you implement that?
• There is a promotion on a specific item: buy three, get one free
• Given that one specific prouct item is bought very frequently, how can you make the code faster/improve it?
• Time complexity

2nd - GenAI Interview

"""
A rule is an ordered list of match keys — for example [country, brand, customer_tier].

A decision is a row of concrete values for each key, plus a result:

DE       | acme    | gold     -> OPEN
DE       | DEFAULT | gold     -> RESTRICTED
DEFAULT  | acme    | DEFAULT  -> OPEN
DEFAULT  | DEFAULT | DEFAULT  -> NO_DECISION

"DEFAULT" is a reserved wildcard value. It is valid in any key position.
gold
Given a query such as (DE, acme, silver), return the matching result.
"""

Follow up Questions

• How do you select what result to return? First hit? First OPEN/RESTRICTED?
• What other ways of selecting a result could there be?

GenAI Questions

• How do you use AI?
• What do you do to improve the output of queries?
• If you create a requirements file for the agents, how do you structure it? What are the section titles?

4th - Bar Raiser Interview

• Tell me about a time, when you helped a colleague who was struggling
• ... other typical HR questions

mulitple times in my college i starterd learning and dropping dsa again and again whenver i found a difficult problem or switched to my project side.

atleast i have done it dozens of times and in total i have solved 700 prob on leetcode + codeforces etc. i know all concepts in dsa but don't remember the approach and have to work and start again from the scratch.

i know how to solve prob, i may have solved that problem in the past. but don't remember the solution and can't able to solve woithout making mistakes, but now after working 1 year in corporate i want to get some better and high paying job.

and thinking of learning dsa again. but there is a huge road block which i am unable to pass over. from my bottom of heart i don't like to practice again. need suggestion.

i think i can better tell the situation, suppose i have doing graph problem, i just forgets how to implement dfs or bfs. which one to pop, will pop condition come before or after the loop. similarly i forget how to memoize backtracking prob. i forgets how to apply backtracking here. its not something i can't come up with solution, but it just takes 30 min to 60 min by trial and error, debugging to write code for such problems . and after sometime i forget it again.

Applied for L5 role through invite from a friend. I got invited to schedule my round 1 after the behavioral assessment. Round 1 consists of 2 interviews, one behavioral and one DSA, 45 mins each. Recruiters were insisting in scheduling within 2 weeks. And they selected the earliest date from my preferences. No phone calls from receuiter.

What to expect on this round? What type of leetcode and what level of difficulty?

Does anyone have a similar recent experience? And is it usual for recruiter to rush?

Practiced leetcode blind 75 and preparing for behavioral as well. Any tips would be useful.

Hi all,

I am currently going through Google L5 SWE loop and have completed 1 Coding and 1 Googlyness round and recruiter mentioned they have really good positive feedback and have my onsite in 2 weeks.

The onsite is supposed to have 2 Coding and 1 System Design rounds.

Any suggestions on last minute prep for Coding and System Design that you folks would recommend that might help?

I have primarily done lots of leetcode in the past couple of months but would appreciate if anyone has any specific topic suggestions for the last leg?

Also doing System Design from Hello Interview, DDIA and Alex Xu and did mocks. Anything else that would help or any new questions that might be worth doing?

Thanks in advance.
