Capital One Senoir Software Engineer interview questions

I had a very good experience in the process. The interview questions were good but I didn't optimize the code well. The other technical interview was a kind of uncommon, it was about the cost of regression test interms of budget. I have never thought of this scenario when I was preparing for the interview.

Basically the exact same as what is said in other posts but I'll reiterate because thats what I would have wanted. Applied online took 3 weeks from start to offer. After applying I spoke with a recruiter and answered a couple questions about my resume. I then was sent a 2 hour long online assessment with 4 coding questions. Leetcode style, I would rate them easy, medium, medium, hard. I only completed the first 2 questions and had barely started on the third by the time the timer was done and I still moved on to the final round so don't stress too much. Final round is "power day" 4.5 hrs long 4 hour long interviews with a 30 minute break. 2 technical, 1 case, and 1 behavioral. System design technical - Design a credit card paymemt system. Basically a use case with API, DB, and UI. Give as much detail as possible and listen to the recommendations the interviewers provide. Coding technical - Couple of coding related questions. ie. What is encapulation? Given an array of integers output the two integers that sum is closest to zero. Geeks for geeks has a similar problem you can practice. Case - 3 sections : Conceptual, given different sprint timelines what kind of testing would you suggest, simple or rigerous. Math, given the cost of the simple and rigorous testing with this budget would they stay in budget? Coding, given this batch script what issues do you see in the results and how would you resolve those issues? Behavioral - 3 tell me a time when... you had to shift priorities, disagreed with your manager, and had to learn something new. Overall not too difficult of an interview if you prepare. Enjoyed everyone I talked to and recieved an offer 3 business days after the interview.
