They contacted me via email. The interview was about 2 hours long. I interviewed with 4 people individually and got a tour of the place and where i'd be working at the end. The people were very nice and asked a lot of questions they went in depth into the company and how they are progressing.

I was interviewed by 3 different people that were to be my boss depending on which area I was hired for. It was one after the other and about 5 minutes each. I was then given about a 30 minute tour of the building and was told more about the company. It should be noted that I started out as a contractor so I didn't get the regular interview process that most hires go through.
