The interview process went quite well. I got a phone call from the head of the combustion department and he told me about the projects available which matched my profile. He asked me my educational background, my previous experiences and my motivations relating to the project. The interviews lasted about half an hour and he told me he will get back to me with a decision within few weeks. After 2 months, I got the acceptance letter for the 6 months internship at the combustion department.
