At first there was a phone interview with Talent Aquisition, followed by a personal interview at their office in Hamburg. After that I got one on ones with a handful of people, from different teams and in different positions. Last step of the process was to hold a presentation on a topic of my choice. Everyone I met at the Trade Desk was perfectly nice and after each interview I felt more and more at home there. Talent Acquisition was always a great help and checked in with me after every single interview as well. What I loved the most about the process, that lasted almost 4 weeks, was that it didn't feel that long, because I got really quick responses (the next day, two days tops) and was able to ask questions and prepare for the next interview.
