The whole process took 2 months. First, the application platform is a pain to work with, shares users with internal platform, shares resume and motivation letter across applications... Interviews : one with each team you might be working with, then a final one with an HR rep. They won't be asking very technical questions, more about your curriculum and previous experiences. The process was excruciatingly long (almost 2 weeks between each interview), the HR dept seems unable to set appointments at the time slots you specified them, and always calls, even when you ask them not to. I needed to ask them several times to get updates, and they never answer at the time they promise you. Overall, I don't feel much respect towards future interns.
