  • Four Onsite Rounds, All Staff-Level InterviewersTesla · Backend Engineer · Senior+ · Onsite · Jan 2026

    Phone screen, 45 min: design a ticket-master system. We went deep on how to prevent double booking. The interviewer also cared a lot about UX — what the API returns, what seat map the frontend shows once it gets that response, etc. Onsite: each round was 45 min. The email told me who the interviewer was and their title, but not which round would be system design vs. past-experience. It was schedu…

  • Four Onsite Rounds, No OfferRamp · Software Engineer · Onsite · Jan 2026
    Rejected

    Coding (I'm posting the full original question) Given a list of flights: Part 1: get_user_with_most_flights() Part 2: get_user_location(time) The problem itself wasn't hard — a classic binary search question. But I had to figure out on my own how to import the file (the file and the test weren't even in the same folder), and I wasn't that familiar with writing tests in pytest, so I spent some tim…

  • Four Onsite Rounds, Rejected After the System Design RoundAmazon · Software Engineer · Senior+ · Onsite · Jan 2026
    Rejected

    Timeline: referral, then a recruiter call two weeks later that set up the phone screen for a week after that, then the onsite (four rounds) a week after that, and a rejection two days after the onsite. Overall impression: the coding difficulty wasn't that high, basically all LeetCode Medium, and every round asked Leadership Principles (LP) questions. I think what got me in the end was System Desi…

  • Four Onsite Rounds, Rejected on System DesignCoinbase · Frontend Engineer · Senior+ · Onsite · Jan 2026
    Rejected

    I interviewed in March. I couldn't find a virtual onsite interview writeup for Coinbase Frontend Staff level on the forum. There were four rounds total. The questions themselves weren't that hard, but the bar was high. Tech Execution: Write a dropdown component. I'd suggest looking at a UI library's props beforehand, something like Ant Design. In this round you need to pay attention to reusable d…

  • Full Onsite Loop, Then Grilled About Using AI MoreDoorDash · Software Engineer · Onsite · Jan 2026
    Rejected

    DoorDash's full loop. I felt like their question bank isn't very big — pretty much everything is covered by write-ups here already. Specifically, the phone screen with the interviewer: dasher_pay. Same problem that's already been posted here, so pay attention to handling the input datetime. I used a few states to control the order's status. I forgot the follow-up, but again, the situations posted…

  • GPS Trivia in the Recruiter Screen, Stuck on "move" in the OAJerry.Ai · Software Engineer · Online Assessment · Jan 2026

    Recruiter Screen The interviewer was really friendly. She started by walking me through the company, then asked if I had any questions for her. In the middle she threw in an unusual question: how GPS works / the underlying design. Roughly, how GPS works, how the signal propagates, and why errors happen — for example the difference between the satellite's atomic clock and the clock on your phone.…

  • HackerRank OA Then a Tradeoff-Heavy Phone ScreenUber · Software Engineer · Technical Screen · Jan 2026

    I finished the Uber OA and did the phone screen too, so sharing both. The OA was on HackerRank, camera required. First question: a Hard DP problem, a variant of a well-known Jump Game problem where the jump-step rule was changed to a prime-number condition. I got stuck for a bit but eventually worked it out. Second question: Pipeline Throughput, solved with binary search on the answer. You're giv…

  • HackerRank OA, Then a Robotic HM Screen and a RejectionPoint72 · AI Engineer · HR Screen · Jan 2026
    Rejected

    A recruiter reached out to me first. After the phone screen, they sent a HackerRank OA — three questions total, 90 minutes. The first question was a lot like one I'd seen in another thread, just with the scenario swapped out. The second one was a LeetCode question. The third was a prompt-engineering question with five sub-parts. Basically: you're an Olympic champion's coach and you need to help t…

  • HR Call Through a Full Power DayCapital One · Data Scientist · Onsite · Jan 2026

    Round 1: HR Call Asked about "why this company," and otherwise it was just some basic logistics confirmation. Round 2: Data Challenge This was done on CodeSignal — about 4 questions total, using numpy, pandas, sklearn, etc. It was split into a few parts: data cleaning, feature selection, and model building. Finishing the data-processing part within the time limit (90 min) was fairly difficult; yo…

  • HR Ghosted for a Month Before the Virtual OnsiteExpedia · Software Engineer · Senior+ · Onsite · Jan 2026

    I interviewed for the global payments team. The phone screen was in mid-February, then HR just ghosted me. I emailed to ask about the result and only got a reply five days later. The virtual onsite ended up landing almost a month late. After the self-introduction in every round there was a small Expedia values behavioral question. Round 1 was coding with the interviewer — a LeetCode question. Aft…

    Phone screen (Coding) Question: Print a binary tree, using * to represent missing nodes. Leaf nodes need to be separated by one space, and then going up, each parent node should be placed in the middle position between its child nodes.

  • Inside the Hiring Assessment's Judgment SectionGoogle · Software Engineer · Online Assessment · Jan 2026

    The assessment has two parts. The first part is the same as what earlier posts already described, so I won't repeat it here. For the second part, since earlier posts only mentioned it briefly, let me say a bit more. This section gives you a scenario and asks you to pick the action you'd be most likely and least likely to take. Here's what I got: You had a good idea about YouTube's design that you…

  • Interviewer Late Both Rounds, Then RejectedByteDance · Machine Learning Engineer · Technical Screen · Jan 2026
    Rejected

    I interviewed with ByteDance's Compliance Team (based in Singapore), for an MLE position. Overall the interview experience was pretty bad. Let me start with the process: Round one: the interviewer was 5 minutes late, then spent about 40 minutes asking about my project in a lot of detail. The coding question was Maximum Product Subarray, which I solved right away. Round two: the interviewer was 15…

  • L5 Technical Screen, Rejected Over the BQ RoundAmazon · Data Scientist · Senior+ · Technical Screen · Jan 2026
    Rejected

    In 2026 there have been almost no Amazon DS interview write-ups here on 1point3acres — I'm starting to wonder if they're on a hiring freeze. I'm writing one up so people have something to reference. Around mid-March I had applied to 2 AS (Applied Scientist) roles. A recruiter reached out to me on LinkedIn and scheduled a recruiter call a few days later. On that call they told me AS roles are most…

  • Marketing Lead-Scoring Case, Offer in Two WeeksIBM · Data Scientist · Intern · Technical Screen · Jan 2026
    Offer

    After I submitted my application, I automatically got sent an OA — one Python question and one SQL question, not too hard. First round (mainly asked about my resume, a deep dive into the ML project on my resume, and a case): What's your experience building a statistical model and a machine learning model? What kinds of variables/features did you use? Did the client only care about the results, or…

  • Merge Intervals, Then Course ScheduleBytedance · Software Engineer · Technical Screen · Jan 2026

    The interviewer was looking over my resume while I gave my self-introduction, and after I finished he asked about a project from my background — a project building a model, and he asked about offline evaluation for the model. Coding: given a set of time-window intervals, merge all overlapping intervals. Input: [[1,3],[2,6],[8,10]], output: [[1,6],[8,10]]. My approach: first sort by each interval'…

  • Nailed the Case Study, Still Rejected After Round OneRoblox · Data Scientist · Technical Screen · Jan 2026
    Rejected

    (QS 50-100 school, physics PhD, desperately job hunting.) First round, technical interview, 60 minutes. The interviewer asked about my resume for 5 to 10 minutes first (my own work also has some connection to DS). Then two simple pandas data-processing questions using a bit of basic statistical test knowledge. I didn't need to run test cases, I just had to make the interviewer understand my code.…

  • Navan Senior Software Engineer interview with a flight aggregation LLD roundNavan · Software Engineer · Senior+ · Online Assessment · Jan 2026
    Rejected

    I went through a compact two-round process for a Senior Software Engineer role, and it ended in a rejection. The first step was an online assessment with two medium-level questions, and I had to use Java. After that, I moved to a low-level design round. The language requirements were strict there too: Java for part of the interview and Java or Golang for another part. The main prompt involved des…

  • Offer

    I had a single-round interview that felt pretty straightforward. It started with a general question about my background and career path, then moved quickly into a classic "hardest" or "most challenging task" question. I was also asked about any previous clearance and defense-related experience, which anchored the conversation. There weren't any complicated coding challenges or deep discussions of…

  • Onsite Loop in the Ads Org: Topo Sort, System Design, and Two BQsNetflix · Software Engineer · Senior+ · Onsite · Jan 2026
    Offer

    I passed this earlier this year, for the Ads department, which has been pretty popular lately. Since I'm planning to accept the offer, I'm not going to post the specific questions — search for the last three months of posts here and you'll find they're almost all the same type. I'll share some experience and feelings that I hope will be useful. Process-wise: they got back to me 1 day after the ph…

  • Onsite Loop With ML System Design, BQ, and an AI-Enabled Coding RoundMeta · Machine Learning Engineer · Onsite · Jan 2026

    ML system design: One question was a common one — nearby place recommendation for mobile users who might be on the move. The other one I hadn't seen before — notification ranking. These notifications come from various products, like new product announcements, friends' new updates, and ads served by advertisers, and so on. BQ: Right off the bat they had me talk about my most proud project. Then th…

  • Passed a Coding Round I'd Seen Before, Then Walked AwayAtlassian · Software Engineer · Onsite · Jan 2026
    Withdrew

    I was contacted on LinkedIn. At the time I was already interviewing with several other companies at once, but I replied anyway to give it a shot. I passed the phone screen, then scheduled the onsite (VO) with the recruiter. Their onsite can be split across several days — day one is coding. If you fail the coding round, they don't move you on to system design. The first coding round was actually a…

  • Passed Onsite and Core Value, Now Waiting on Team MatchAirbnb · Software Engineer · Other · Jan 2026
    In progress

    I got laid off in the middle of last year, unfortunately. After that, looking at my mortgage, I felt empty and pessimistic for a while, then started grinding practice problems hard. At first I used a bunch of small companies to warm up, but I was rusty and kept getting rejected all over the place — I was almost losing my confidence. Then I finally got an interview at Airbnb through a referral. Ai…

  • Passed Round 1, Failed Round 2 After Solving Two of Three ProblemsBytedance · Software Engineer · Technical Screen · Jan 2026
    Rejected

    Round 1 was a coding round with the interviewer, and the experience was great. It was conducted in English, one hour total: the first five minutes were quick self-introductions, then 45 minutes of coding, and the last 10 minutes were for me to ask questions. The problem was a LeetCode question — the exact name was obscured in the original post, but it involved some kind of transformation. I walke…

  • Passed the ICC Screen, Then Turned It DownPilot · Software Engineer · New Grad · Technical Screen · Jan 2026
    Withdrew

    The first round went by quickly and I got the contract offer — March 16th, in Python. I heard the batch is about 15 people per batch. Some background on me: Ivy League school, ECE switching into tech, class of 2026, new grad, no internships, GPA 3.8, a few ML school projects. I've been going for SE/SDE/SWE roles and honestly feel like I don't have much in the way of skills or experience. I went t…

  • Passed Two Fraud Rounds Despite a Rocky PerformancePayPal · Data Scientist · Onsite · Jan 2026

    I applied to a few PayPal positions before Christmas, and two of my applications got recruiter calls. One of them was for a Fraud DS role and moved to interviews fast. The interviewer was someone from the same team based in India, and the interview was at 10:30pm Eastern. They asked about fraud, statistics, SQL, and Python. The second round was with the hiring manager, also based in India, at aro…

  • Password Validator and a Three-Table Join Over Bad AudioKarat · Software Engineer · Technical Screen · Jan 2026

    Weird screen, hard to categorize, but I hope this gets seen anyway... Classic low-quality Amazon-customer-service-tier microphone. I've worked with people like this for years and I still only understood about 50% of what the interviewer said. Fortunately they noticed too, so I politely asked them to speak a bit slower, and it got a lot better after that. Right at the start they said I didn't need…

  • Phone Screen Plus a Four-Round Onsite, No Feedback After Two WeeksVerkada · Software Engineer · Onsite · Jan 2026
    No response

    Phone screening: HR sent an environment setup prep ahead of time, asking me to set up my GitHub account beforehand and install Docker / PyCharm etc. locally. The interviewer was very patient and walked through the whole flow end to end — I needed to implement three API calls. The actual question matched a report I'd already seen in another thread on the forum. Onsite, live and in person: I drove…
