First, a pre-screen phone call with the HM, then passed a timed aptitude exam, then finally a four person at once interview. I'm not sure what that exam proves as far as work performance; it was excessive and not easy, but I passed it. The interview was fairly friendly, however it had canned thorough questions that are nearly difficult to answer on the spot, but I was able to answer them. I thought I did quite well through out the whole process. Then a week later I got a follow up call, right before the HM was going into a meeting, so when I called back I was not able to reach them, but they said to give a time they could call the next day, which I did. They then did not call back during that time, but at a much later time. So after over 24 hours of false hope, they finally called me to tell me I didn't get the position. Probably one of the worst callback experiences I've ever had, an email would have been fine.
