PayPal Senior Developer interview questions

Hacker earth test followed by 1 Technical coding interview which is very simple followed by design round and Hiring manager round. The first round was very easy. You just have to give the algorithm and not necessarily a working code. 4 questions were asked in this round and I was able to answer all of them. The second round is supposed to be a design round but the interviewer did not join the scheduled call for three times straight in a row. I was kept waiting on the call forever and only after contacting the recruiter came to know that the interviewer is on leave. The third round is a Hiring manager round. Th ehiring manager seems to be pretty uninterested in the candidate or the interview right from the beginning. He was putting the candidate on hold and was chatting with someone during the interview. He seems to be very arrogant. Does not even seem to care about knowing the candidate's profile before the interview.
