Phone screen, director phone screen and then in person interview. Not too difficult as long as you seem like you really want the job and you're confident you'll be good at it.

I applied online and I was contacted for a phone screen within a few days. At the end of the phone screen, I was scheduled for a 45-minute phone interview with the Director of Sales, which included a role-play sales call. I was contacted the following day to schedule a final on-site interview, which lasted about 2 hours. Everyone I came in contact with was extremely helpful and friendly, and the turn-around time was exceptional. I really enjoyed my time on-site, and they really went out of their way to make me feel welcome. My one critique of the process is that the phone reception during my phone interviews was poor and I had trouble understanding some of the questions.
