I was contacted by a recruiter and had a 30-minute phone call to get an idea of which group I would fit best.

About a week later, I had a 30-minute phone interview with the lead engineer for the group I would be working with. He asked about my resume, then asked a few technical engineering questions, and then let me ask questions and told me about the job.

After a few days, they set up a second interview with another engineer on that team. It was also about 30 minutes, but he jumped right into technical questions to gauge my engineering knowledge. There was a little bit of time at the end for questions.

A little under a week later, I got a call from the original recruiter offering me the position.

Be able to talk about your background, problems you've tackled before, and how you solved them.

Know your fundamentals regarding whatever position you're applying for.

For mechanical-type jobs, know basic structures, fluids, heat transfer, etc.
