The campus recruiter from BASF was very nice and and professional. The interview was conversation based, asking candidates how they would handle certain situations and to know how candidates have handled particular problems in the past. There was a greeter before entering the interview room, and I find that to be a bit awkward.

Just 1 interview, between you and the hiring manager. It lasts 30 minutes. Had to be rescheduled a few times. Not too serious on their part. Was promised feedback and did not get any.
