Submitted an application online which was pretty thorough. Then I had a phone interview with mostly behavioral questions, and a few on how to increase profitability. Nothing too difficult. Over 500 people apply and only 20 made it to the final round, so remember to show how much you want to work for them. The final round of interviews is in their New York office and the whole event is called "A Taste Of L'Oreal." You have to get into teams and work on a case study with four questions and present it to the l'oreal team. While the questions itself weren't that difficult (profit margin, break-even, cost analysis etc. Know your excel!!), there was EXTREME time pressure, and having to work in teams and divide up work evenly is stressful. Don't take over the whole project, make sure to integrate everyone. Then, there is a 2 on 1 interview. Again, normal behavioral stuff, a few cost analysis questions.
