three rounds: one bq interview, one oa, one final interview. The bq interview is just some general bq questions and the oa has five questions in 1 hour. I think the time for the last question is not enough though

You want to say you outgrew your previous companies and that is why you won't go back and want to continue to grow with Veeva. Otherwise, you will not pass the phone interview. They heard that my previous company wanted me back but were unable at the time, and rejected me because they think I will go back afterwards.
