~2 weeks after application was contacted for a phone interview. Pretty simple overview of the position and my background. Was then asked to come up to Boston to interview and meet the team. Although I was there for 5 hours it was a pretty relaxed process, no difficult questions. Met with several people to discuss the position and how my background met the requirements

First was an initial phone call. Then I had an interview with the manager and team member where they got to know me a bit. Next was another interview with a team member where we talked about more technical things, immediately followed by an interview with 2 team members. Then I had a final interview where I delivered a presentation to 6 people.
