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.
