The entire application process was very well structured and you were informed promptly by a recruiter after each step about any further procedures. The recruiters themselves were extremely polite and reliable. In my case, there were several interview rounds and a challenge. The questions and tasks were fair and appropriate to the time frame. I have also been in other application processes besides Celonis that have dragged on for an unpleasantly long time... For me, the application process at Celonis was one of the best I have ever experienced so far. Therefore, great kudos to the recruiting department from my side!
