TiVo interview questions

Recruiter reached out for a position in Durham, NC. 1st round: Interviewer was manager of the team. behavioral one. I was selected for next round. 2nd round: telephonic. Asked a bunch of core Java questions. Interviewer was cool. Selected for next round. I was told this is final one. 3rd round: 3 interviewers joined. (2 new guys+the guy who was in the telephonic). Asked about projects, why looking for job now and a simple sorting question. Wrote it and explained it. They wanted me to open ide. I wrote in notepad. The telephonic guy was happy. Other two were surprised why I wrote on notepad. Recruiter reached out for one more final round. 4th round: 3 new interviewers joined. Same format. Project and coding and why are you looking for a job right now. I realized from the moment interview started that they were angry and they were there to find a reason to reject me. When I wrote the program in notepad instead of eclipse, one guy did scold me. He seemed worried and frustrated through out the interview. I then even took the code and ran successfully in eclipse. I realized, they were frustrated as they were not able to find a reason to reject me. Recruiter never reached out to me to tell me that I was rejected. After a month, I reached out to him. He said, I was not selected and can give me reason if I want. I said, Ok give me the reason. He never replied.
