PTC QA Engineer interview questions

The interview process consisted of a phone interview, then an in-person interview with various people representing QA and Development. It was a bit disorganized but but the interviewers asked good questions. I was asked how I would test a specific piece of equipment given a very limited amount of time, tested on SQL and XML knowledge, and asked to QA a sample UI interface. I found a real bug during the sample QA, so that was kind of fun.
