For the sephora inside JCPenney job, I submitted my application online thru the jcp website. They later called me to set up an interview. On the interview they ask you the usual questions like why you want to work there, a situation in the past when you've provided excellent customer service, how you handle a difficult customer, etc etc. It wasn't a difficult interview. I went dressed in a business casual outfit with my makeup done. Not too heavy, but making sure it looks like you spent time on it. You don't need prior professional experience with makeup or anything, but being interested and excited about makeup and skincare is a must.
