First, speaking sincerely, if you've got the best of intentions, then good luck. I think you're crazy, and up shit creek without a paddle, but good luck.
Second, think hard about getting used to this type of treatment, some of it will be locker room banter, but it could just as well be mean-spirited dickheadedness.
You are asking to be put at the bottom of a professional ladder. Some of the people you may work for may shit all over you for being more qualified than them. Others may shit on you just because you rub them the wrong way (like you've already managed to do). Or because they're just in a shitty mood. Not saying it's GOING to happen, but I've seen other who were successful in their professions join late, and get jaded real fast about being treated like children.
