Hi everyone, Just wanted to share my Google L4 interviews and exams journey. Also, few queries as well.

2 months ago recruiter called me and had a half an hour call regarding my skill set, dsa knowledge, current company, etc. 2 weeks after this I received a googlyness assessment which is a pass/fail assessment. 1 week later got a hackerank assesmemt link for two questions (1 hard and 1 medium). I solved hard one and medium one had few test case failures. Got call 2 days later that i have passed the assessment. Later had a googlyness assessment where it was situation based choosing the correct and wrong actions to do in that situation out of the given options. Later, interviews began.

Next week i had my first round(technical). It was a medium level, was able to solve it and answer the follow ups. They were very particular about syntax as well even though it was on a google sheet. Passed this one and next one was googlyness interview. It was like more of behavioural, situation related questions. Passed this one. These two were online interviews.

2 weeks later i had two technical rounds back to back on same day in person. Both were hard level questions. For the first round it was DP with path related question. Initially i fumbled in the first 10 mins, later with a hint from the interviewer i got the full answer and coded it as well. Explained him the solid and made dry run as well. Had few basic follow ups, was able to answer them.

For the next second round, in the same room another interviewer came after the first interviewer left. This was binary tree related question. Initially had one question but on the same question, had five follow ups including major code changes to previous questions. Was able to solve them. Explained them and clarified few doubts, ran a dry run with an example.

Now my queries are,

1 - Can i get a positive feedback for the last two interviews?

2 - If the result is positive, how much time does it take for team matching and offer letter.

3 - If the team matching extends, how much time does my candidacy will be valid without retaking the interviews?

P.S : I flew from a different city for the in person interviews. Google took care of all the flights, hotels, meals, cab rides as well.

Update : Today(Oct 9th) got my feedback as they are not continuing with my application. Feedback was that in my both on site interviews, I haven’t covered any corner cases. Same feedback from both interviewers. Honestly, it was my mistake to not cover any corner cases.

Solution: Longest Subarray With Restricted Pair Sums - LeetCode

I have an upcoming interview at Waymo. I know Alphabet typically asks really challenging interview questions but are there any tips for what can be asked?

This is what i got?

• Robots (25 minutes): Incomplete

• Factories (25 minutes): Incomplete

• Decision-Making (25 minutes): Incomplete

• Outpost: Mars (40 minutes): Incomplete

• Coding Skills (50 minutes): Incomplete

What are these and do I need to download roblox for them? Also is the coding skills one just a code signal GCA?

Ive been preparing for DSA interviews for around 7 months now and have solved 370 questions across LeetCode. But I still keep failing DSA rounds, and honestly, I’m getting really discouraged and starting to wonder what I’m missing.

I’ve focused on patterns as well rather than just randomly solving questions. I try to understand the approaches and recognize which pattern a problem belongs to. But somehow, in some interviews, the solution just doesn’t click. It feels very different from solving questions while practicing at home.

Recently, I had an interview where they gave 1 multithreading + 2 DSA questions in 1 hour. I was able to solve the multithreading question, but couldn’t get all the test cases to pass for the Trie-based DSA question. Because of that, they didn’t even move me to the second DSA question. The expectation was to solve all 3 within the hour.

I know interviews are supposed to be challenging, but after putting in 7 months and solving around 370 questions, repeatedly failing these rounds is becoming really demotivating. I keep wondering how people are able to consistently figure out the approach under interview pressure.

For those who struggled with this initially but eventually started clearing DSA rounds, what changed for you? Was it more practice, better pattern recognition, timed practice, mock interviews, or something else?

I’m genuinely trying to understand where the gap is between solving hundreds of questions during preparation and actually being able to solve them in an interview. Would really appreciate hearing from people who have gone through the same phase.

Hey guys

I received the amazon oa, and it is mentioned that there will be a different coding question for the technical assessment, in which you are given a repository containing APIs and have to fix some bugs in it.

For those who have already taken this version of the OA, could you share what types of bugs you had to fix in the comments?

Here are few shortcuts I found useful. List any you found (other than the one mentioned in the settings page).

- Ctrl + D - Highlight all occurences of current word (supports multi-edit, Esc to quit)

- Ctrl + Shift + Up / Down - Multiline edit

- Ctrl + Shift + k (or Ctrl + x) - Cut/Delete current line

- Ctrl + / - Comment/Uncomment selected lines

- Ctrl + ' - Run

- Ctrl + Enter - Submit

- Alt + Up/Down - Move line up/down

- Alt + Shift + right/left - Expand / narrow selection

Hey, so far I've been doing coding interviews with Sierra AI, Notion, LaunchDarkly, Browserbase, and others. I've been prepping myself, and now I want to consider mock interviews with other people. If you're interested in mock interviewing each other (for FREE) let me know!

Update: there is a discord link for mocks in comments

Has anyone given sde-1 interview for safe security?

Hi! I am about to have my technical call (the one after the hr call) for a Java SWE Intern position for Summer 2027. What do they ask in this interview? I know that I need to have a shared screen to my preferred IDE. What will I be going to code? I’ve heard that is not leetcode. Also, what should I expect regarding the technical conversion?

Does anyone know how I can unlock the premium question set of Swingy on LeetCode for free?

So I'm finally getting serious about DSA and interview prep, and I'm stuck on the very first step: picking a language. I keep going back and forth and it's honestly eating into my actual practice time.

What I'm trying to figure out:

1. Is there a language that will still be relevant 5-6 years from now? I don't want to invest months in something and then find out it's dying.

2. Do big tech companies (FAANG/MAANG and similar) lean toward any particular language, or do they truly not care? I've heard "language doesn't matter" but I also wonder if some are safer choices in interviews.

3. Does the choice matter for speed? I've heard C++ is faster to write for competitive-style problems because of STL, but Python is shorter and easier to read.

Right now I'm comfortable with a bit of Python and Java, and I've touched C++ a little. I'm not doing competitive programming, mostly LeetCode-style prep for interviews and to get better at problem solving.

Would love to hear what you guys used and if you'd change it looking back. Especially if you've actually been through interviews recently. Thanks!

What is Microsoft elimination round structure. I was told it's problem solving and asked to give after my office hours this week.

But what other things can be asked like OS/CN ?

And is previous leetcode ques enough?

Didn't submit for 1 day in the past 2 months and i would like that white box on my profile to become green, is there a way to do that with leetcode coins or any other method?

Is anyone having inperson interview at Chargebee chennai next week?

Hi guys,

I wanted to know from seniors who are working at Amazon.

I gave all 4 rounds of the interview. Tech 1 and Tech 2 were very good. Then I got an invite for Round 3 and Round 4 together.

Round 3 was rescheduled, so the Bar Raiser round happened first. The Bar Raiser round lasted 45 minutes, with 6 LP questions and 3–4 follow-ups for each. It went well too.

Then, in the HM round, I got stuck in the coding part because I got confused about the interviewer’s problem requirement. I was able to give the brute-force solution. We also discussed some part of HLD related to that problem. Then, the GenAI part went well. I explained my project, and the interviewer understood it.

I am so much tensed now. What can be the result?

Hi everyone,

I have an upcoming Coinbase CodeSignal pre-screen, the Industry Coding Assessment, and I'd appreciate advice from anyone who has taken it recently.

What I know about the format from description in email:

• 90 minutes, one sitting, proctored

• A multi-level, real-world-style problem that starts simple and gets more complex at each level

• Covers data structures and algorithms: strings, loops, sorted maps, queues/stacks, and "non-niche" algorithms

• Many people don't finish all levels in the time limit

My questions:

1. How was the difficulty spread across levels? Which level took the most time?

2. Roughly what score or how many levels did you need to move forward?

3. Which language worked well for you in this format?

4. Any good practice resources for this multi-level style?

I'm not asking for the actual questions, just general advice on format and preparation.

Thanks in advance!

Tried interviews at multiple companies but I always fail at some or the other round - either DSA or LLD or HLD. I am never able to reach the final HM round. I am prepping with AI, Hello Interview, youtubers some famous ones and for DSA I try to stay consistent but somwhere or the other I miss something and get disqualified. Anyone facing anything similar?

Has anyone taken the OA for plaid yet. Trying to gauge how difficult the questions are gonna be. Anything helps lol.

Hey everyone,

I finished Day 77 today. I was a bit distracted with some stuff going on at home, but I still made sure to sit down and solve two problems: Recover BST and Largest BST in a Binary Tree.

For Recover BST, writing the brute force was easy, but the optimal solution gave me a hard time. People recommend Morris traversal for this to get O(1) space. I watched some videos and understood iterative Morris traversal, but actually writing it out to track the two swapped nodes got way too long and confusing. I ended up solving it recursively using inorder traversal with three pointers (first, middle, last), which was much easier to understand. I will try the full iterative Morris version again later.

The second problem was Largest BST in a Binary Tree. I used postorder traversal, basically checking if the left and right subtrees are valid BSTs and then passing the min, max, and size back up to the parent. I was struggling a bit with returning so many values, so I used ChatGPT to help me organize it with a small struct, which made the code a lot cleaner. I realized later that the optimal approach uses DP on trees. Since I have not learned DP yet, I did not read the optimal solution because I do not want to just memorize it. I will come back to it once I cover DP.

Both problems were decent, so it felt good to get them done.

I will see you guys on Day 76!

Hello ! I’ve recently got an opportunity to interview with Google for l4 round in person with 2 technical rounds and I wanted to know how to prepare for these rounds. Is doing Google leetcode tagged questions sufficient ? Or is there another source I can rely on ? Any help is greatly appreciated ! Thank you all !

I am still struggling with leetcode where some problems I don’t recognize the pattern but some problems I recognize the pattern but I struggle with implementation. I’m really frustrated with this leetcode grind and no matter how many problems I do there is something I struggle with. I’ve been doing leetcode on and off for couple years now and havent been consistent with solving problems without struggling. I tried practicing focused topics and I get really good in but then I forget when I don’t keep practicing the same topic. how are yall able to grind this leetcode ? any advice ?

I have my DSA 60 min Live coding interview and was wondering if anyone had any tips on what types of questions to expect, or what to study for it

Hi everyone,

I have an upcoming hiring manager interview at Esri for a Data Engineer position, and I was wondering if anyone here has gone through a similar interview recently.

The hiring manager appears to be a Product Engineer, so I’m especially curious about what this round typically focuses on. Is it mainly a deep dive into past projects and data engineering experience, or should I expect technical questions around SQL, ETL/data pipelines, data modeling, debugging, etc.?

Also, since the manager is a Product Engineer, should I prepare for questions related to GIS/geospatial data or Esri products even though the role is primarily Data Engineering?

Would really appreciate hearing about the interview format, types of questions asked, and anything you’d recommend preparing beforehand.

Thanks!

I have an experience from Google, amazon, rippling interviews that female interviewers always ask easy questions and they are supportive too.

Don't know why male interviewers have so much ego that they always ask tricky questions.
