Weingart Center interview questions

The interview was during a "Job Fair" event which was located at their rooftop parking lot. They had coffee and baked good snacks while we waited. The interviewers for QA had not shown up during the event. The event lasted 4 hours. Finally within the 3rd hour I was told their was an emergency and that the interviewer was not going to show. I gave them my name and number to reschedule and they never called back. This was a complete waste of time.
