I applied online. I interviewed at Capital One (Richmond, VA) in Mar 2026
Interview
After you complete the OA you get a brief questionnaire from a recruiter and then you are invited to "Power Day" where you schedule your final round interviews. There were 3 interviews that were conducted back to back, technical, case, & behavioral. I interviewed March 2026, waiting to hear back.

Question 1
The technical portion was a 4 part parsing question that build upon itself. They let you choose what data structure to answer the problem with, you then walk through data parsing and storage, fraud analysis, and output formatting. The case interview was talking through a chatbot implementation where you are given scenarios and you have to discuss them, and then analyze and fix some buggy code based on that. Lastly Behavioral was standard, it was three questions: Tell me about a time you went against the status quo? Explain to me a time you worked well in a team? How do you approach learning new things?
Smooth, standardized interview process with 1 OA, 1 Hiring Manager round, 4 rounds for Power Day (Case Study, Technicals, Role Play, Job Fit).
You have one HR supporting throughout, generally quick to get response.
I applied through an employee referral. I interviewed at Capital One (New York, NY) in Sep 2025
Interview
I was referred by a friend. Whole process took a few months. Tech screen was through an automated site called CodeSignal. This was followed by a "Power Day" (4 hrs of interviews): Technical, System Design, Creative Problem Solving, Behavioral.
I passed the interview and was waiting for team-match, which never happened. After a few months, I was notified that they didn't have any open roles and to try again in the Spring.
