Three stages overall. A HR phone screen which was pretty standard, a more technical phonecall and then a 3 hour interview (over Skype) with multiple employees. For the most part it was a good experience. Unfortunately I really choked on the last round during a core technical question and I knew it wasn't going to work out after that. Most of the people were very nice, though the people conducting the technical portion of the interview seemed pretty cold and uninterested. I also felt that a couple of their questions were a bit unclear, but overall nothing terrible.
