A good chunk of the CM's that worked at the boutique during my CP were either full time, part time, or seasonal and about a handful were in the college program. Its one of those roles that is very hard and very sought after to get (next to an entertainment role or working at haunted mansion or tower of terror).
When I applied to the college program I had had tons of experience working with kids (you don't always have to), I had been in theater, dance, and skating so I knew how to do hair and make up (once again, you don't always have to but it helps), and I had also had experience playing a part (you have to play it up BIG at the boutique).
I think Disney looks for the following when looking for boutique:
-Female (that's a big one)
-able to keep their "character"
-upbeat, whimsical personality with some sparkle.
-patient but able to multitask and multitask quickly.
-being able to think on your toes. You could get a Princess in your chair that falls asleep while doing the hair (I've had that happen quite a few times), has a tantrum, is shy, is scared, won't talk, speaks another language. ANYTHING could and will be thrown at you so it helps to be good at improvising.
Don't be afraid to really let the personality shine and come out in the interview. That will really help!
If you have any other questions, please let us know.
OP [PixieDustPrincess] Any tips on your end of experience? Where did you work?
