Applied through a recruiter for a French speaking role. Three rounds - a translation test of English to French and French to English on the luxury goods market, 60 minute online case study followed by 2 video/phone interviews with HR and a team manager, then face to face interview with senior manager and service director. A lot of questions on research skills, interests in business and knowledge of databases. For the mini studies and the curveball question, the key is to be logical in your process.
