Autodesk Developer interview questions

I Had multiple rounds and all interviewers were really friendly and the process was really comforting. First one being telephonic, another one was coding round with 2 developers and last one with the head of department. So overall a good experience with the interview.

The interviewer was unfriendly . It felt like he was trying to reject me asking high level questions wantedly and tough interview for 2 years experienced that too for contract based job.
