The M&G with IAH CP is super chill. As I am sure you have already heard a bunch...just be yourself. this is very true. It is really a get to know "you" session and if you are going to be a fit in the United pilot group. He is a very nice guy and really just wants to get to know you. Feel free to PM me and I would be happy to share my experience more in detail. I assume you already have it scheduled?

Good Luck!
