None of the questions were all that difficult and they mostly pertained to what I spoke to them about. With a program manager interview if you are confident and have strong interests in something specific, then steer the interview to a that interest. For example, I have a lot of interest with collaboration in China and whenever I brought that up, they used scenarios that had to do with doing business with China. It was great. The last interviewer asked me to design a calculator, which is a question someone else received in the glassdoor reviews so I would prepare for that one.
