JPMorganChase Java Senior Developer interview questions

Interviewer started the interview with a question on my status. He asked questions for 5-10 minutes mainly focused to find negative points in my resume. Instead, he should have concentrated on my knowledge on the subject. Then a new guy joined the call and started the questioning without introducing himself. I answered all the questions but I got rejection after 2 weeks of the interview. They are doing interviews just to fill the positions they have already elected. They have some internal candidates and just what to prove we are not able to find any good candidates.
