I applied on L'Oréal Career website for an offer in Geneva (I uploaded my CV and wrote a cover letter) Then the day after my application I got a phone interview with the HR. Basic questions about my curriculum, about the cosmetics market (also the Swiss market for cosmetics). After the call I got an invitation to the Assessment centre at the local headquarters in Geneva. In total there where 2 sessions with 8 candidates each times (so 16 in total but I think it was for 2 different internship positions). Most of them where French Business school student applying for a gap year or a final year internship. The assessment center was in French in 3 parts: 1. Working on a problem in a team of 3 members (it was about how to organise effectively a plant knowing that anyway there was not enough space..) 2. Négociations. The 3 of us had different projects in different countries/areas... we had to define a budget for each knowing that budget was limited. 3. Face to Face interview with a member of L'Oréal Team. Unfortunately I spoke with the HR again so nothing really new from the phone interview... It took half a day.
