30 minutes long 1 on 1 with mid-level engineer. Behavioral only questions related to background, projects, and experience. Interviewer asked maybe about 10-15 questions related to design and manufacturing lifecycle. You are interning for a team within a team within a department.

Was able to talk to representatives at college career fair, and got invited to a first-round interview. Was over video for about 30 minutes and was pretty standard behavioral interview. A little less than a week later got invited to final round interview. Two days; first day was just information presentations on company history/values, the department I was interested in, and culture. Second day was two 30 minute interviews (although I know for others it was three). First one asked some general questions and then shown a cross section of a tool and asked some thought process questions (How do you think this works, etc). Second one was more background-oriented, and more behavioral/teamwork focused. Be sure to mention if you are interested in a particular area, as they will make a note of it. Offer was given via a phone call early the next week.
