I was directly contacted by HR because I was from a target school in Lisbon (IST). I had a small interview with a very friendly person from HR and it was very chill. She explained the process and asked normal questions (personality, projects, hobbies). For the final stage, they organised a big event in their office with everyone that passed through (~200). They divided us into teams of ~5 and we had a small project that we had to work on and do a small final pitch. At the end of the day, there was a final interview with a partner. The questions were still personal but a little more complicated. Here are some examples: Favourite and worst course/area, if I wanted to never code again or be locked without talking to anyone on the job, one time things went bad for me, why should they hire me. And other people told me there were little brain teasers like how many lamp posts for a highway between X and Y or what's the angle that the clock pointers make at a certain hour.
