It was totally i biased interview. Interviewer had some work to do so he left after interviewing 3 people and we were total 8. He selected 2 out of 3. Then another interviewer was arranged, he asked about program complexity and that's it, Nothing else. He took interview of 4 people including me and rejected all. Afterwards one guy was left behind and no one was there to take his interview. After waiting for 2hrs, they sent a guy to take interview and rejected him as well.
