OM BPM interview questions

Since this is a startup, I was not willing to give interview. But on HR's request I had given the interview. Almost all the questions were answered correctly and in the end the interviewer have asked me about my current CTC and expectations (he has not supposed to asked it). I was calling them to know the feedback but they were not picking my call and answering my messages. So don't tell you salary or expectations to person other than HR.
