Applied through a posted DM contact. Preferably a French speaker since the work is mainly in French. Despite my intermediate level, we went along anyways. I had two interviewers who have been nice but were clearly disappointed because of my French. I had an interview online but I would not recommend it to do it that way due to a poor microphones in their room (personal opinion)

In the morning: interview with 2 sector analysts (motivation, previous experience and competency questions). A 30 minutes case study. And an interview with a senior M&A banker in the afternoon.
