It's a great place to work during the holiday season! If you already have a full time job working cash or operations sound like a good option! I actually really liked operations since you have a lot of different options for working hours. Wear all black to the job fair, something a Sephora employee would wear. When you're seasonal you have to wear your own clothes, they don't provide you with a uniform. Also, wear a full face of makeup that you think makes you stand out! When I was working there they had a rule that you had to wear a foundation, at least 2 or 3 eyeshadow colours, a lipstick, blush, and your eyebrows done. They're pretty good about hours if you have another job! Good luck if you decide to go through with it!
