Initial interview, then ProveIt test, technical interview with a programmer, then a in person interview with a final technical interview. The test was pretty difficult java questions. More questions on libraries than I was expecting. They happily paid for a plane ticket but the day before the flight they decided to call to cancel the interview because they decided not to hire anyone and get rid of the entire project. I was very disappointed and quite confused about it since the entire interviewing process took a month and had no indication that the position was questionable to exist.
