Got introduced to this opportunity by a recruiter -mistake #1 already. The first call was with their 1000x certified technical expert at GWL. He was nice except in his one and only technical question the guy actually made an incorrect statement about unit testing. He sounded a little surprised when I told him why he was wrong, but nonetheless he tried to stay dominant. I didn't want to argue and moved along.
Anyway, got the green light from the guru and was scheduled for a second call this time with the manager. But when I called in he apologetically told me that an "urgent meeting" had come up and we needed to reschedule. Told this to my recruiter. He apologized and said he'll let me know. It's been 1 month since then.
Bottom line: very unprofessional interview process.
