I feel that the main thing I pulled from their discussions is to not be single-minded and always consider the reasons behind an action; always plan ahead, always be prepared. If a student isn't behaving how you would expect, don't immediately write them off as an awful person or a slacker, consider the possibilities behind their attitude, and work around this in order to get through to them. And being prepared is important in everything of course, but I hadn't really thought about how an interview is a chance to show an employer what YOU know about the company... Really important idea, I'm very glad they came and told us these things.
