I just applied for mcwork online, I didn't need to print anything yet. You check if you have been accepted online also. So until you are hired thats all you need to do.

Does anyone know how many people usually apply for jobs through McWork? I sorta wanna know my chances of getting hired =P

I went to see one of the ladies at career services, and she told me they look for your experience and skills to match the job. So if you have that then you should at least get an interview!
