Got into the office and the interview was later than scheduled. Got into the room and was blinded by a test (excel, LSAT type questions, math, etc). Didn't even know if I could use a calculator for the math portion (not basic math)...directions were pretty unclear. Talked to a few guys; they were okay to talk to but it seemed as if they didn't really care. Talked to the CEO (who was late)....he was extremely rude and kept interrupting me every time I would try to answer his questions. Poor, poor interview process. To make things worse, they never bothered to follow up with me in about the position. Extremely unprofessional.
