I passed their online assessments and was reached out to with dates for a power day that would be 4-6 weeks later. They sent me potential dates, and I responded on the same day. Even though I bumped my recruiter multiple times, I didn't hear back until 4 weeks later (the earliest date they had offered me for my power day), saying "all slots were full" and that they would reach out to me later regarding scheduling a power day interview. They didn't get back to me except to tell me months later the only location they had available was one I had vetoed early on in the process and to ask if I was still interested. By that point, I had already accepted another job (a hiring process that only took 3 weeks from start-to-finish, might I add). Overall, the power day process was extraordinarily unprofessional and rude. If you apply to Capital One, expect to get ignored, ghosted, diresgarded, and left hanging - even if they want to move forward with you as a candidate.
