Personally, I was a little undecided on the occupation since I didn't have much in the way of details to pick from. If I had some idea of exactly what the YC is and what positions or occupations exist at this point in time, I could more decidedly put something down.

I already planned on changing skills since I had afterthoughts matching what you just said.

Edit (11/26/14 01:20 CST): Changed skills, awaiting more information on occupations.
