I first interviewed for the position at the conference and then I was lucky enough to make it to the second round. I was flown out to Redmond and was given a rental car, hotel room, and meal compensation. The interviewers were spilt from morning to afternoon and I got morning. It was an interesting process since it was 4 interviews back to back starting from 8am to 12pm. Each interview lasts about 45 mins each and then followed by a break time. One of the interviews was a presentation. The questions are behavioural with a twist. I enjoyed the questions because they were not the normal "tell me about a time..." but more engaging. I only ran into one interviewer who really tested me about the industry and my side projects. Overall I really enjoyed my experience and hope to interview with them again for full time.
