This was one of the best interview processes I've been through, mostly thanks to the HR replying to all my questions very quickly and pro-actively getting back to me. It was a 3 steps process: a phone call with HR and then 2 individual interviews (the first one on Skype with my manager located in another office in Europe and the second one in person with my other day-to-day manager in Paris, which was also the occasion for me to see their offices). People were very nice and the interviews weren't very technical as it was "only" for an internship. However, they did check my previous experiences and ask a few questions about my personality.
