Pros
Working around beauty products all day is fun if you already love makeup/skincare/haircare/fragrance. It feels good to help people find products that fit their specific needs. I never used the discount to buy anything I didn't need or already knew I liked, other than a couple of things when employees got special extra discounts.
Cons
A retail job is a retail job. If you don't have a salesperson personality a lot of the things that happen will bother you, like they would anywhere else. You will constantly pushed to encourage customers to buy hundreds of dollars in products they don't need or want, pushed to get them to sign up for credit cards to save them cents on a purchase just to increase your store's numbers. I made it pretty clear to my managers that I was working during school and didn't live a frivolous lifestyle, but they would still try to get me to buy things like perfumes and Dyson products that were worth more than some of my paychecks. This is probably specific to the store I was working at, but my manager would stop people from trading or taking over shifts if the person who was giving up a shift didn't have a "worthy" reason. Ex: I was stopped from trading shifts with a coworker because my manager was aware that my coworker had plans to go on a small vacation that weekend.
