Capital One Senoir Software Engineer interview questions

Unstructured interview where if you are not Indian and within a certain caste, then you will not get hired. One of the interviewers asked me how to design a Reservation system, which I got into the details and then he stopped me. Then he started asking me questions that even he couldn't even understand him, things such as Java validators. He asked me any question he can find in the book to fail me. MF, why waste my time if you didn't want to interview me? For the use case, I was asked why do companies do acquisitions, and then he gave me a code and asked me debug the logic.
