Very relaxed and comfortable process. There was a reception the night before where you were able to speak with several hiring managers in a relaxed enviroment.
The next day you had an introduction followed by 4 separate 40 minute interviews with different managers. Mixed questions, standard STAR and technical, nothing too tough. Real easy going.
Recieved a phone call an hour after the daylong process from recruiter, already have a tentative offer pending 1 more reference confirmation.
Company paid for everything, flight, car, meals,was treated very well and pleasant experience.
