6 interview long process, however very good to check for right fit both for Celonis and candidate. The process includes a challenge interview requiring proper preparation of a few hours.

3 Interviews, 1 hr, 1 hiring manager and one case. It takes more than 30 hours, you have a pre round to practice with a company employee that told me make my prediction more pesimistic. Then when I presented the case they told me my predictions were pesimistic so it wasn't good.
