I got a phone interview through a personal reference. They talked about what the job and training process was like, asked me to expand on some things in my resume, asked if I'd had a chance to look at the website and read their core values etc (I had fortunately!) and we talked about that some. They set up an in-person interview at the end. There was nothing really technical.

Young engineers are brought in for a full day to speak with engineers with varying levels of experience. The interview process is intended to be comfortable and open. Lunch is provided.
