Passed the OA. Then there was a power day: 1) Design session (design a system); 2) Java coding session (no LC); 3) Very straightforward behavioral session (STAR/CAR); 4) The last one and the weirdest one – case study interview where you have no idea why you are doing that.
My case study interview was very confusing. Yes, it's nonsense to do this exercise for this role, but I see that it's a regular interview process at Capital One. I recommend not overthinking the exercise – there is no catch, just do what you asked for.
But overall good experience, everyone was nice to me.
I applied online. The process took 2 months. I interviewed at Capital One in Apr 2025
Interview
The process was long and unnecessary. First you get a screening call and then finish an online assessment. Afterwards if you pass you get set up with a meeting with a manager type, then if you pass that stage you have to go through 5 rounds of back to back interviews during their "power day" and good luck if you get someone that's done other interviews already bc they'll be tiered, uninterested and hard to talk to. Then once you're done with ALLLL this you'll get ghosted for 2 weeks just to be told they cant extend an offer to ANYONE bc they dont need to fill this job in anymore... And this enire process took over 2 months at this point...
Interview consisted of 3 parts: behavior and two technicals.
Behavioral was standard "tell me about a time" questions.
Both of the technicals were leetcode design easies. The second technical also had a portion that gave a business case and required me to think through the costs and benefits of implementing software for that case.
