It was a pretty quick and simple process. I had only 1 interview with several engineers that fair questions about my experiences, skills, knowledge, etc. It was relatively casual and straight forward.

In person interview with company president and a senior project manager at the HQ office. The interview lasted for about 45-60min. Was told to expect to hear back within a week or two, but ended up receiving a call about a day (or two) later during which I was presented with an offer.
