I was contacted by a hiring person and interviewed the next week.The interview was with three different people over about an hour and a half. It was almost purely incredibly hard technical questions too specific to ever have been covered in school. I never got an offer but I wasn't disappointed because of how poorly the questions were answered and how bleak and closed in the office area was. I was contacted the next week with an email saying I wasn't going to get the offer and why. It was very professional of them to follow up in that manner.
