CodeSignal OA With Hidden Tests and a Painful ID Check

Fresh OA from an hour ago!! Background: I don't need sponsorship. A small side story: uploading my ID took forever this time. Maybe the lighting was bad, or because I was holding the ID right up against the camera, but it kept telling me it couldn't read the text. In the end it only verified after I screenshotted an old passport scan from a folder on my computer. Luckily I wasn't in a hurry... Ev…

Power Day with Behavioral, Case Study and Agentic Coding

Sharing a recent Capital One TDP Power Day interview report. The Power Day had three rounds in total: Behavioral, Case Study, and Agentic Coding. The Behavioral round was pretty standard, basically all classic BQ. As long as you prepare a few projects ahead of time and tell the stories clearly with the STAR framework, you should be fine. Teamwork, conflict, and failure are especially worth prepar…

System Design With a Phone-Scrolling Interviewer, Then an Offer

After three months of interviewing, I finally landed a Lead Software Engineer job at Capital One. A bit of background: I've been the lead engineer at a fairly small company for close to ten years, and almost everything I know came from doing the work. I had barely touched LeetCode-style problems, and my system design knowledge came only from the systems I'd built at my job. To get through the tec…

Power Day with Case, Behavioral, Coding and System Design

I just finished the C1 power day. There are already plenty of OA write-ups on the forum so I won't go into that, I'll mainly talk about the four power day rounds as a reference for anyone interviewing later. The four rounds were case, behavioral, coding, and system design. The case was the virtual card number one, which someone has posted about here before. First we talked about the benefits and…

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…

Four-Question OA Where the Rotting-Oranges BFS Ate My Time

Posting this a while after the fact. I strongly recommend doing them in the order 1-2-4-3. People on the forum did say 3 was kind of hard, and I got stuck on it for ages. I'd have been better off doing 4. To explain: the easy questions up front take roughly 25 minutes, and then two mediums in 45 minutes is still pretty hard. You're better off getting full points on one of the last two questions..…

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…

Four CodeSignal Tasks Without a Recruiter Call

The author reports receiving a four-question CodeSignal assessment from Capital One without prior recruiter contact. One task involved a basic array operation, but the author could not recall its details. The other tasks concerned alternating high and low values around a circular array, identifying a smaller pattern within a numeric matrix, and determining whether segments fit on a number line co…

Four-Question OA, Left Q3 Blank and Tripped on the Digit-Swap Problem

Catching up on a write-up for the C1 AI Engineer OA I did a while back, which I failed. 4 questions total, 1 hour 10 minutes. The first two were really easy. I can't remember what they were, but they were just really easy, you can finish them in 10 minutes. I didn't understand question 3, so I skipped it and went to do question 4, and in the end I had no time to come back to it, so it was complet…

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…

Four CodeSignal Tasks and No Reply After Nearly Two Weeks

It has been almost two weeks since I finished, and I have not heard anything, so I probably failed... This was the first interview of my job search, and I never expected to fall at the OA. Looking back, I did not take it seriously enough, did not prepare enough, and was not familiar with this OA format. There are many interview reports on the forum, so I am writing about a few things I had not se…

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…

New OA With Four Questions, One I Only Half-Solved

One hour and ten minutes, four questions in total. Question 1 Very simple — take a string and reorder it by first character, last character, second character, second-to-last character, and so on. Input: abcde Output: aebdc Question 2 Also simple — a string made up only of W, D, L characters. Sort the whole thing so the output repeats in W, D, L order.

Same OA, Now Cruise-Themed Instead of Superheroes

I noticed there isn't much here about this OA, and I just finished mine, so I wanted to share. The two Canada-version posts from 2024 are completely outdated now — what's being tested currently is very similar to another report I found. Basically the approach for every question is the same, except it's no longer about superheroes, it's about cruises now. There are 12 questions total, but the firs…

Capital One Software Engineer interview: CodeSignal OA under time pressure

My process was dominated by a CodeSignal OA where time pressure mattered a great deal. I completed the assessment and earned full points on three of the four questions, which was a relief, but the clock was already working against me by the time I reached the last one. The OA had four DSA questions in 70 minutes. I fully solved questions 1, 2, and 4 and got top marks on each. When I reached quest…

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: 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…

Product Manager interview at Capital One

I started with a phone screen, then a Virtual Job Tryout, a mini case around a Capital One product, and finally Power Day. Recruiter communication and the materials made the sequence somewhat predictable, but there were enough checkpoints that mistakes still felt costly. Power Day meant four back-to-back one-hour interviews. I worked through a case tied to a product I had worked on, product round…

Capital One Data Analyst interview: SQL and final business case

After a recruiter screen, I took an online technical test and then went through rounds that felt much more business heavy than advertised. The test had one basic SQL question and a larger set of data-manipulation multiple-choice items. The first interview mixed business-case work with a very quick SQL component, and a later technical round had easy LeetCode-style questions. The mismatch showed up…

What are interview experiences?

An interview experience is a candidate's own account of a hiring loop — not a question bank entry. It tells you the shape of the process: how many rounds there were, what each round actually tested, how long the gaps between them ran, and what the recruiter said at the end. That context is the part a question list cannot give you.

How to read them

Weight recent write-ups more heavily — interview loops change, often within a year. Read several for the same company and role rather than one: a single account tells you what one interviewer asked, while five tell you what the bar is. Note the outcome badge too, since a rejection write-up usually explains the gap far more precisely than an offer one.
