First, you complete an online coding assessment prior to talking with anyone. Talk with recruiter. Coding interview. Finally, half-day round including coding round, system design, case study, and behavioral interviews.
Not much hard, but very focused and have to solve problems during the interviews. The interviewers were polite and ensure your success. Initial CodeSignal round with coding that need >=50% scoring, followed by 4 in-person rounds which they call it as Power Day. Fast tracked.
I applied online. The process took 4 weeks. I interviewed at Capital One (Cambridge, MA) in Dec 2025
Interview
2 recruiter calls and an initial technical screening, followed by Power Day, a 4 part interview session. 2 technical components, a case study, and a behavioral interview. They pretty much tell you details of each step before hand.
