It was a fairly lengthy interview consisting of interviews between three groups. The first group included a technical interview where they had coding exercises and specific code related questions. The second group was more of an in depth perspective of my previous experience with technologies. The third group asked more questions about previous working environments. After all of the interviews, it ended up taking around 2.5-3 hours.

Phone screen then on-site interview, 4 interviews, one behavioral, three technical. Very quick-paced, decision after the interview within a week. Not too many company specific questions, though I was coming from a different industry so they perhaps didn't expect me to know too much, especially considering it's more a b2b company so I hadn't used it obviously.
