I applied online. The process took 2 weeks. I interviewed at Capital One in Jan 2015
Interview
Coding online then if you pass, statistics and big data questions with a data scientist. Coding interview on hackerank is difficult. I believe that it is only suitable for a software engineer position; you have to use concepts from dynamic programming etc to solve the questions. Really irrelevant. After which you go on to be interviewed on stats and data analysis then if you pass you get invited to the office and interviewed again using case studies. So you get questions just as tough as a software engineer does, then get questions just as tough as a statistician does, then get questions just as tough as a business analyst does. What do they think, that data scientists are unicorns? It seems that the new process just got rolled out this year. I think that those who got through before this new process were lucky.
I applied through an employee referral. I interviewed at Capital One (Dallas, TX) in Jan 2026
Interview
I had an interview with the hiring manager, and she started to ask about my CV and went through the details of each project, and also asked additional questions about each project, what would happen if we do this or that
The recruiter call me and after a 30 min meeting with HR they set me up for interview with the manager, but no one showed up and they never responded my email
Two technical rounds with case studies and coding + SQL. Coding was just LC easy level and SQL was a bit more challenging but being comfortable with all the key words should be good enough.
