Hi!
I was an account manager for BeneFit in a House of Fraser store for 18 months. Most of the girls are employed by the particular brand they sell, but BeneFit and Guerlain girls, and maybe some others, are actually employed by the store, so it's worth contacting the store as well as the cosmetics companies. Also try local temp agencies, we had loads of girls in our store who temp'd, and one got a permanent job out of it. I got my job because I was such a regular customer at the counter, we got friendly and the girls told me about the vacancy!
BeneFit in particular is a very hard counter to work on as they expect you to 'traffic stop', ie stop customers elsewhere in the store and bring them over to the counter, and hold regular promotional 'parties' when they whack your target right up! They also like you to keep customer record cards and call the customers regularly and ask them in for makeovers etc. It was a lot of hard work, while all the other girls; Clarins, Dior etc don't have to do anything like that!
BeneFit is a lovely brand of make-up, but as far as working for them goes, my advice would be go for someone else unless you really have loads of energy and confidence. I left because I just couldn't keep it up anymore! :zzz:
Generally speaking, it's a good job to have. I've known girls get given Chanel earrings, Dior bags etc, and you get your free allowance of products every 3 months.
Good luck hunting! Hope you enjoy your new job...xxx
