How does Capital One virtual credit card numbers provide value for Capital one?
It was ok, brush up on interview styles like consulting cases, be able to sovle a mckinsy case with ease, and you'll be ok. I messed up on some calculations (although I rectified myself) but wasnt able to land the offer
There was an online assessment followed by the first round which is a mini product case (from one of Capital One's products like Shopping, CC). They provided a lot of preparation material for the case.
