First, they had me fill out an extremely redundant questionnaire of approximately 50 questions. It asked the same question multiple times and ended up being 10+ pages long. Afterwards, there were a series of Skype interviews. The first one, was a general interview. The following two were a "mock presentation." The final round of the interview was a 8 hour long interactive day of activities, games, tests and whatnot. After all of that, they did not offer anyone the job. They said that they ended up hiring more experienced hires recently and were no longer in need. In other words, they dragged us all through 5 rounds worth of interviews and then would not own up to their own HR mix up. It was extremely unprofessional and inconsiderate.
