    I applied through college or university. I interviewed at Capital One.

    Interview

    Behavioral -> Case -> Technical
    I think the interviewers were professional and made the process go very smoothly. The most challenging part is the case interview since it is the only one you cant really study for.

    Easy Interview

    Application

    I applied through a recruiter. The process took 2 weeks. I interviewed at Capital One (Boston, MA (US)) in July 2020.

    Interview

    Round1: Phone interview with a recruiter/HR.
    Round2: An online, automated, assessment via Hacker Rank.
    Round3: A three hour interview with three different people, back to back via Zoom. No break.
    Round4: An interview with a manager via Zoom.
    It was awful. I withdrew my application. For round 3 they send an email saying your interview could be any time between 9:00AM and 5:00pm. They send you another email the day before the interview of what exact time it is. Who thought 3 hours of back to back interviews was a good idea? I didn't get a break. The fourth interview was supposed to happen the same day round 3 but the interviewer rescheduled and I wasn't notified.

    I applied online. I interviewed at Capital One.

    Interview

    Capital One recruiter has a tendency to ghost on potential candidates if they are not interested.
    At first, the recruiter calls you and asks you to take a coding challenge.
    Two coding challenges are presented through HackerRank.

    Also, the recruiter/HR is very helpful on how the interview will be if they are interested in you. They have a guideline on what to expect.
    Due to the Covid-19 Situation, the final interview is completed on a Zoom Video Conference application rather than onsite. Four interviews that consists of two technical tests, behavorial, and a case interview. All four interviews are 45 minutes long. Due to employees working from home, one interviewer made the interview a little bit difficult to concentrate, listening to a screaming kid from the background.

    One technical interview has leet code questions and the other technical question is supposed to be a white board question. But due to the interview not being onsite, the interview was more about my resume/technical background.

    Behavorial interviewer asks 3 questions. Interviewer expects about 12 - 15 minute length answers using the STAR format.

    Most were easy to talk to except one who seemed agitated.
    Overall, they were nice, but deceptive.

    Application

    I applied in-person. The process took 3 days. I interviewed at Capital One (McLean, VA (US)) in April 2020.

    Interview

    Initially there is a hacker rank coding quiz which consisted of two questions testing your problem solving abilities. However, after passing the quiz, I had an interview with a hiring manager that I can only describe as bizarre. The questions raised some red flags for me and even if I had received an offer, I would have declined it. I have serious concerns about Capital One management if this interview is indicative of the software engineering management team.

    Application

    I applied online. I interviewed at Capital One (Plano, TX (US)).

    Interview

    Applied online. Got a phone call from a recruiter with super basic questions about my work eligibility status, why I want a new job. Did a code round online (2 hacker rank questions) then went to onsite interview they call a power day (4 interviews 45 min each) and then they followed up 2 days later with a result.

    Interview Questions

    • Q1: Bunch of standard behavioral questions. Talk about a time when... questions.

      Q2: Case question: Capital One acquired an online bank IGN. What are the business/tech benefits of this acquisition? What are the challenges? They asked me to walk through a snippet of code and determine what it was doing. It was a function to determine "eligibility" for an offer to customers. 3 Variables into a function that had a bunch of cascading if/else statements - some were redundant. You need to make a truth table to figure it out. Then analyze the output of the truth table and refactor the code into a few lines.

      Q3/Q4: Technical background questions. They asked me mostly about my background and the things on my resume. Then quizzed me on questions like - what would you do if you had this table and wanted to get the second-highest value in this column how would you write the query? You have data in s3 file how do you update some of the values in s3 efficiently? How do you deal with spark driver-worker memory? What is a DAG in spark? Difference between GroupByKey and ReduceByKey? My interviewer said she tried to be a data scientist but it was "too hard" and then asked me DS algorithm questions which I answered to a level of detail she probably didn't have the knowledge on and she seemed impressed. She asked me about gradient boosting, how to tune an algorithm, what my favorite algorithm was. Asked me about SQL window function if I ever used one.

      I was pretty surprised I didn't get an offer because I answered almost all questions with good level of technical knowledge but if you go on Reddit and search for the capital one you'll find out they are a "fake" tech company and they've rejected plenty of candidates that got offers from real tech companies. They are looking for people who will drink the cool-aid. I asked my interviewer where they are in terms of automated deployments and he said they have a good portion of manual deployment and people doing SQL updates/inserts as a process. That sounds like a "real" tech company to me!   Answer Question
