The BBB is an EXTREMELY competitive position. The most competitive, I think. They only take the very best. My friend got BBB her second time around and is a FGIT right now, and she says there are only 10 girls total who are FGITs on the CP. Out of the thousands that applied, only 10 got accepted.
Other roles, however, may be easier. If you ask for Attractions it's a lot easier, than say, Front Desk, which is more competitive. Attractions has a lot more spots.
