Long but not too difficult. Did 3 rounds and talked to different departments - friendly people (best part of the company is its people). Expect to go through hr and then someone from your department + line manager.

Went through 4 great interviews, enjoyed speaking with the team from DC and Boston. After last interview, I received an auto-message that I did not receive the job. I asked for feedback or why but didn't hear back from anyone. Also had submitted a "practice" itinerary for free. After all that time and free work you'd expect some sort of follow up.
