Pros
L'Oreal is a widely recognized name and seems to induce French romanticism among female audience. 50% in company stores for products ranging from Lancome, Kiehl's, Ralph Lauren fragrances, Armani fragrances, Matrix, Redken, Maybelline, Garnier, etc. Also, there are bi-monthly "free goods" available from company stores. Good opportunity to impress people with products (cost of goods is minimal) bought at half off.
Cons
Salary and benefits are below industry average. The R&D buildings at Clark, New Jersey, are falling apart. And the new building is no where in sight. Some buildings have serious OSHA violations, such as fume hood being vented back inside the building, lab coats are building worn outside of lab areas, dubious record keeping. Unless you're French-speaking (for example, French-Canadian, native French, French-American), then you're out of luck.
