I applied for an intern opportunity posted on the intranet of my university and sent my CV directly to the manager. Just one round interview in Paris. A Normalien en Mathématiques was the manager however, he was very kind and the questions were based on what you have written on your CV. After this interview, I got the offer a week later for the internship.

before telephone interview, there were a several tests, such as English competency test and Quant Specific subject test. Quant subject test was all about mathematics and probabilities. And it follows a telephone interview
