I had a total of two interviews. The second interview was the day after the first interview. I got an offer via email about a month later. I accepted the offer and started the position two weeks after I accepted the offer.

I was interviewed by 5 people, 1 was the site leader, 2 were group leaders, and 2 were department leads. They ask an array of questions from: explain how a cooling system works, name and describe as many components as you can on a diesel engine, and typical engineering questions like what was the last engineering project you worked on, etc.
