Merck Process Engineer interview questions

Initial HR phone interview followed by 4 one on one interview that lasted about an hour each. Interviews consisted of providing my background, reasons for interest in the position, additional info on the position and some hypothetical scenarios.

Campus interview with rapid-fire direct questions. There was no conversation or rapport before questioning started, so it seemed as though they were only interested in my qualifications and not me as a person. There were 2 interviewers who were both process engineers (no HR rep).
