First round is campus interview. The interview goes for 30 minutes (10 minutes talking about myself, 15 minutes conducting a case study, 5 min asking questions). Second round is phone interview is given by employees from the specific track that I applied.

only made it to the first stage which was a phone screening. I spoke with a hiring manager in HR, who would have made the interview as quick as possible, so it is up to you to have questions ready.
