The interview was in two stages, first one was a quick call with the hiring agency, the second stage if you pass the first was to have an in person technical and 1 to 1 interview, so it took around 4 hours. The technical one was almost like a series of games, first a group session coding, then a type of exercise where you have a team of 5 people which splits in smaller teams whit different assignments to do. The 1 to 1 interview was done with one of the software engineers which I found quite nice, almost like a discussion.
