Really bad communication, the interview was also 2.5 hours long and 30 min of technical questions on heat transfer, tolerance stackup, engineering design process and find whats wrong with the drawings. I was also sick so it was horrible time there. That was onsite.

First had a phone interview with HR as a screener I assume, then I got a second interview scheduled in person. In person interview included a few people. First person I talked to was manufacturing floor manager, then engineering manager, then mechanical engineer manager. There was a small skill assessment with some basic heat transfer concepts, some tolerance stacking questions, and a "spot the errors on this engineering drawing" question.
