Hi!
So I think Bakers has a bank of questions that they use. I remember that when I did the VI for the spring vac they were very different questions from the one my friend got when she did hers about a week later. That being said, you can expect to get three competency questions (mine were mostly surrounding teamwork and time management), one commercial question and one "random" question - there was one question along the lines of "tell us something that would help us understand you better."
Hope that helps!
