Pros
As an employee of a retail company, you can use employee gratis or discounts to purchase products from your brand, as well as LVMH's other brands. You may receive goodie bags throughout the year filled with expensive products or samples. If you work in a retail storefront, you'll get to try consumable products (perfumes, makeup, lotions, liquor, etc.) during product launches. If your division is doing well financially, you can enjoy lots of free coffee and the occasional catered lunch.
Kontras
LVMH is old as dirt, as you can tell by its dated legacy systems and its glacial pace of adapting to change. If you are not a middle-aged woman or French, expect to be a minority wherever you work in this company. Compensation is average, vacation allowance is the lowest I've had at any job, and the healthcare options are limited and slightly overpriced IMO. LVMH certainly looks like a good employment experience on a resume, but the high employee turnover I've witnessed seems to indicate otherwise.
