Pros
L'Oreal is the big entrance to the cosmetics industry. Gives knowledge and insight, allows you to work as the market leader with the retailers. Informal and fun corporate culture. Provides opportunity of responsabilty and execution to anyone - there is much to be done and job descriptions are vague. Extending one's influence is up to you. A great start to a career, after a few years at L'Oreal you are an asset to many companies. A passionate industry to work in, innovative. Allows exposure to top management and to influencing directly the results of a product launch very soon in one's career.
Cons
Very fast paced around product launches. Office politics a must to work your way around issues. Guidance is vague many times, must be able to 'figure it out'. A tough culture for newbies, takes a while getting used to, getting the means to do your job, knowing who does what. Standards of execution are not set straight to entire teams, it's a company that allows each employee to fill objectives in the way they see fit - this has it's pros and cons. High employee rotation. Recognition is achieved by not only doing excellent work, but also by being able to show it off in the right way.
