Also, I would add that, in a big company, you should try to work with people as high up as you can, even if you're intimidated.<p>People high up either say "yes" or hand you down to someone who can definitively say "no." If they say yes, the people below them are directed to make it happen.<p>People not high up enough either say "no" or hand you up to someone who can definitively say "yes." If they say no, the people above them never hear about it.<p>So clearly, dealing with people higher up improves your chances dramatically.<p>Brad Bird was the one who I first heard point this out: "Oftentimes the people at the top are really fun and the people on your way up are really fun, but there's something about a lot of middle managers -- people that don't have the power to say yes but do have the power to say no."
