Two interviews: one HR, one with an engineer. The first, HR, was to get to know more about personality and background, and was half in French, half in English (internship in France). Questions were about why I applied, what were my strengths and weaknesses and what experience I had in teamwork. Second interview was more technical, with more details about the expectations of the internship. There were some technical questions about Lean, and others regarding skills in implementing macros with VBA.
