I applied through university. The process took 2 months. I interviewed at ENGIE (Paris) in Nov 2013
Interview
Starts with a resume review, followed by a face to face interview. The interview can actually be followed by a second session, depending on your supervisor. It tends to include a written test to assess your analysis skills. Nothing too scary honestly.
