Is it okay to put down just one position on the form? I don't really want to do anything else to be honest. Thank-you. ;D
Well you can, but there's no guarentee you'll get it. So then, if they don't have a position you want to offer, they might not give you a job! Though I'm sure they'd ask you if there was anything else you'd like to do.
What you need to think about is what you want most? If you don't get that one position, would you rather not go or go and do something else there? Because they might not hire you if you put just the one thing down and it's not available if they think you don't want to do anything else at all.
What are you applying for? For CRP in Canada they asked us to rank the 3 options (F&B, Merch, and Attractions). I would definitely rank all of them if you're asked to. They are looking for enthusiastic people who want to work at Disney, and saying that you aren't willing to do the other 2 jobs isn't looking as enthusiastic as someone willing to rank all 3. You can always turn down the position if you decide you don't want it.
