IDEXX Laboratories Operations interview questions

Unprofessional company. After they wasted my time for as long as a month and a half and three interviews with different personnel, they did not even have the decency of giving me a feedback on the position. They disappeared completely, I asked for an update, via e-mail, and was replied I'd receive a feedback within one week. They never got back to me. Therefore I had to assume I had been rejected. Not the way a serious corporation behave, so make the math.
