Single interview led to offer. In applying for an electrical validation position, they asked me 2 technical questions, one of which didn't actually pertain to the job itself. The hiring manager was present, as well as 2 engineers. Overall, typical questions about previous experirence and how well you work with others.

I received a phone call (which was much more efficient than an easily lost email) that allowed me to set up an interview. The interview process was great, as it was conducted by the actual engineers I'd be working with.
