I applied through an employee referral. I interviewed at Capital One (McLean, VA) in Jan 2020
Interview
There was one phone screening and followed this 6 onsite interviews. Phone screening included several technical question on machine learning and Neural nets. For the onsite, there were 6 rounds, they made me stay overnight in a 4-star hotel. The overall process looked pretty structured.

I interviewed at Capital One (Londres, Angleterre)
Interview
Case interview. The interviewer guided me to calculated answer a series of question. I could not fully understand the question so I asked him a lot of things and he answered me. The case was about lunching a new game which has free vision and pay vision in the market.
This is for a new grad program - a case study (math and stats heavy) plus some ordinary behavioral questions. Quite intellectually challenging if your case is complicated but quite interesting experience. also very nice interviewer overall (not so great at giving hints though)

Question 1
a case study (more like a consulting one but very reliant on math calculations)
It was very good. The person asked me questions and I responded back with answers. It was a pleasant experience. The questions were interesting. I have nothing more to say on the matter.
