Been there few weeks ago, they do the interview at the hotel.
8am presentation at the conference room, then they post a schedule and start calling 1 by one.
There is a panel of 3 for the interview, 1 line pilot, 1 senior pilot and 1 HR representative. They gonna do about 7 questions each, very easy questions, nothing complicated, 30 minutes interview.
11am lunch time, and that's all. They call me next day for the good news.
The gauges available in the internet are very accurate.
Good luck
