Capital One Data Scientist Interview Experience — Take-Home Challenge, Then a Four-Round PowerDay and an Offer in Under 50 Minutes
Yesterday morning was PowerDay, 9:00am-12:30pm Eastern Time. I'm in Vancouver, so I dragged myself out of bed at 5:20am for the interview. Luckily it went well — less than 50 minutes after the interview ended I got an email from the recruiter with an offer writeup, and now the next step is team matching. I've been sending out résumés for a year and a half and honestly it made me want to die, cons…

Capital One Data Scientist Interview Experience — The Energy One Mini Case and a Same-Day Power Day Callback
Mini case, midday on 3/18/2025. The question was one someone had already shared here before — the Energy One case. The interviewer gave a short self-introduction, then asked about my background — worth remembering to prep for that too, I was so focused on the mini case that I answered it pretty roughly. Then we got into the actual case. There's an energy company called Energy One that wants to tr…

Capital One Data Scientist Interview Experience — the Groupon Coupon Mini-Case
Just finished the mini case this morning, and by the afternoon I already had the pass notification along with a scheduled power day for next week — I have to say the recruiter I got this time was way better than the last one. While it's still fresh, let me report back to everyone. Hoping next week's power day goes smoothly. At the start, the interviewer briefly introduced his background, had me i…

Capital One Data Scientist Interview Experience — the Ride-Share Profitability Mini Case
I just finished my mini case this morning, sharing it while I still remember everything. I've gotten a lot of help here, so I wanted to give back too. Hope everyone's interviews go well. Today's interview was the exact question someone here had already shared — the original Google Doc question — and of course that was the one question I hadn't gotten around to preparing. Felt like I'd practiced p…

Capital One Data Scientist Interview Experience — Three Case Rounds, a Scheduling Mishap, and a Rejection
Round 1 had two interviewers — one leading, one silent the whole time. The BQ was a standard "help others" question. They followed up with a lot of detail, including what materials or records existed for the help I gave, and what I had to sacrifice or give up something important to help someone. A handful of other detail questions too. Then came the first case. It started by bringing up the reven…

Capital One Data Scientist Interview Experience — Two Attempts, a Cancelled Headcount, and an Energy Case Interview
My Capital One interview process has been quite a rollercoaster so far — over the past month or so I've interviewed twice. Timeline The first time was through a referral from a friend, for a newly posted analytics role: 1/16: HR Call scheduled 1/24: HR Call rescheduled to 1/31 — the reason was that when the original interview time came, I sat on my phone waiting for over half an hour, then HR fin…

Capital One Intern Software Engineer Interview Experience — Superday With a Case Study and an AI-Assisted Coding Round
The Superday was three parts, behavioral (standard), case study, and AI assisted coding. The case study covered the use of virtual credit cards and had multiple sub-parts. After weighing the tradeoffs of virtual cards, you analyze some virtual card numbers and see what specific conditions they fulfill and you debug some code regarding the conditionals for filtering these card numbers. The AI assi…

Capital One Interview Experience — Three Case Rounds in One Power Day
This is my May interview experience. Since one of the cases hadn't been posted on the forum before, it took me a while to write this up. Round 1: Product case — this was similar to what's already on the forum. Round 2: They asked about the $300 over-limit transaction case, which has also shown up on the forum before. My attachment has it too. Round 3: This was a case I hadn't seen before, and I f…

Capital One Lead Software Engineer Interview Experience — Power Day Across Two Days
I had read the Capital One interview reports on the forum and found them very helpful, so I'm sharing some more details to give something back. It was still the four-round Capital One interview, the so-called Power Day, split into case, behavioral, coding, and system design. I spread the interviews over two days. Day one, case interview: The familiar virtual-card-number problem from the forum, wi…

Capital One Machine Learning Engineer Interview Experience — Four Rounds Including a Virtual Credit Card Case Study
There aren't many MLE interview reports for Capital One on the forum, so I'm writing up my own experience to give everyone a reference point. I'll try to be as specific as possible, hoping it helps other people interviewing for MLE later. There were 4 interviews total, each scheduled for 1 hour, as follows: Set A technical. The interviewer was pretty easygoing, and overall it went smoothly and pl…

Capital One Machine Learning Engineer Interview Experience — Manager Round Ran Long After a Slow OA
This company is really annoying about it — you have to grind through an obnoxiously long OA before they'll even schedule the hiring manager interview. After I finished the OA, I actually had to remind the recruiter myself before they moved things forward. Let me talk about the manager interview. It was basically pure conversation. The manager seemed like a nice guy. He mostly asked what I'm curre…

Capital One Product Analyst Interview Experience — A Recruiter Who Forgot They Recruited Me
In early July, a recruiter reached out to me proactively on LinkedIn, asking if I was interested, and said that if I was, they wanted to talk to me as soon as possible, as soon as possible, as soon as possible. I said sure, and figured the day after next would work. They vanished. Four or five days later, at 6pm, they called me directly out of nowhere (probably because my LinkedIn settings let re…

Capital One Product Analyst Interview Experience — Rejected After Stumbling on the Venmo Case Math
Since a lot of people on the forum helped me out a lot, I'm still posting this report even though I ended up getting rejected, which is a shame. Behavior: The usual three — success, helping others, and failure. Remember to prepare detailed examples, there will be follow-ups. DC: I made slides, mostly focused on visualization, since at my current job I present to an MD every day so this felt famil…

Capital One Product Manager Interview Experience: Power Day cases on A/B testing and profit optimization
After a recruiter screening call, the process quickly moved into a mini case on a Capital One product. I received charts, interpreted the data from an A/B-testing perspective, and then zoomed out to a UX review where I made recommendations from what I saw. About a day later, I had Power Day, a long series of interviews that mixed product skills, product discovery, and heavier case work. One part…

Capital One Product Manager interview: four Power Day interviews and a DMV case
My final stage was Power Day: four back-to-back video interviews. Two were consulting-style cases. The other two focused on product work, including a product I'd led and a product-sense case study. The product prompt involved designing an experience related to the DMV. I had to connect the user journey, decisions and trade-offs into a clear plan. The day felt like an assessment of how I framed pr…

Capital One Product Manager interview: math and product decisions
After an initial one-on-one, I spent a full day in back-to-back meetings, each about an hour long. The split surprised me: two rounds were essentially math problems, while the others assessed how I made product decisions and thought about product work. One interviewer put it this way: if someone is so strong at math that becoming a developer or moving toward technical architecture makes more sens…

Capital One Product Manager interview: respectful conversations about team culture
This was one of the smoother interview experiences I had. The people I spoke with felt genuinely strong, and I liked how they talked about the role and the team I would be working with. The conversations gave me a real sense of the company culture and did not feel rushed past the context. The tone stayed positive, and I left understanding what the job involved. I did not get an offer, but I would…

Capital One Product Manager interview: withdrew after recruiter mismatch
I only reached the early stage because the recruiter call put me off. It felt disconnected from product-manager work and the roles being hired for. I came away thinking the person did not understand what Product teams did, and they discouraged me from taking part in a rigorous full-day process if I did not feel like a strong fit. There was a brief attempt to pull me back into the process, but I h…

Capital One Quantitative Analyst Interview Experience — A Full-Day Power Day Onsite Ending in an Offer
I've read a lot of interview reports on the forums and gotten a lot out of them, so let me quickly share mine. The position I interviewed for was Quantitative Analyst. HR just asked about my visa status and then scheduled an HM phone interview. The HM interview was on Zoom. At first I thought there'd be some technical or resume questions, but it ended up being basically all BQ. A lot of it was ab…

Capital One Senior Business Analyst Interview Experience — A Case Round That Was All Numbers, No Strategy
Capital One Senior Business Analyst When I was prepping for this interview and came looking for interview reports, all I could find were ones for data analyst roles, so I told myself that once I finished mine, I'd write one up to help other people interviewing for business analyst positions. Let me introduce my background first (though probably nobody's interested) — I have a Business Analytics m…

Capital One Senior Business Analyst Interview Experience — Two Cases and a Digital Product Case
After scheduling the interview, I had a phone call with HR. I was explicitly told that there would not be three behavioral questions. The product interview now uses only a digital product, and it includes questions related to AI. Case 1: a 90-day short-term loan. Case 2: wheat. They were exactly the same as the interview reports on the forum. Work through all of them and you will be fine! Product…

Capital One Senior Data Analyst Interview Experience — A 70-Minute, 15-Question OA With Excel, SQL, and Stats
Capital One Senior DA Submitted my application on the 9th and got the OA the next morning on the 10th. Then my procrastination kicked in at full strength and I put it off all the way until today, emmmmm. Overall the difficulty wasn't too high, just like people here have said. It's split into three parts, 15 questions, 70 minutes. You get your score right when you finish, and it logs how long you…

Capital One Senior Lead AI Engineer Interview Experience — Four Power Day Rounds and a Virtual Credit Card Case
I did the four-round Senior Lead AI Engineer Power Day in late September. It felt all right overall. I guess poor performance on the VNC case was why I didn't pass. Round 1 — AI Engineering / System Design Design an Enterprise Agent Platform The interviewer asked a series of AI / agent / platform / system-design questions that were within the scope of my preparation. Round 2 — Technical Case: Vir…
