Capital One Project Manager interview questions

Overall a very poor recruitment experience and I expected better from Capital One. Had I received an offer (I didn’t), the experience would have put me off accepting – this is not bitterness as I have found employment elsewhere shortly afterwards. Started with standard online application form, 3 weeks later I was notified I had been selected for the next stage – a phone interview. Phone interview consisted of the interviewer walking through the role for 15 minutes, then using the remaining 15 minutes to ask 2/3 ‘job-fit’ questions which were your typical behavioural-type questions (‘describe a time…’). 15 minutes was no where long enough to provide adequate answers but nevertheless a further week later I was informed I had progressed onto the final stage, a 3-hour F2F on-site. Upon providing suitable dates for the F2F interviews I waited a further 10 days for a response to the email, finally being provided a date another 10 days in the future (very slow). The F2F day consisted of 3 x 1-hour sessions, a BA case study (entirely maths focussed), a product challenge (reinvent a product and describe a product of your choosing) and a product design case study. After each 1-hour session if there was any remaining time I was allowed to ask any questions on the role. The day is very intense, and I would question how relevant the maths challenge was to the role I was applying for. All interviewers were extremely friendly and tried to make you feel at ease (the one positive from the experience). After the interview I waited a further 10 days to receive an automated email telling me I had not been successful, considering the effort involved would it have been too much to ask for a phone call or at least a personalised email? It’s now been several weeks since the interview and I have still not received my requested feedback. What stuck me was after 3.5 hours of interviews with Capital One, I’d been afforded no more than a few rushed minutes to ask any questions about the role, and only been given ~10 minutes to actually talk about my experience and why I believe I’m right for this role (during the phone interview). Surely this cannot be a sensible way to recruit. Every step along the process I felt like I was waiting around for a response. Would not recommend, the process needs to be entirely overhauled.
