I applied through an employee referral. The process took 3 months. I interviewed at Celonis (Madrid) in Jan 2024
Interview
From the application, 3 weeks until first contact with HR, which was a 30 min interview. Then, 30 min interview with manager, with several technical and business questions to prepare. Then, a challenge was needed. One 30 min "dry-run" session was offered, and another 1 hour real session with managers. Finally, a 30 minute interview was scheduled with an executive. References were also requested.

4-5 rounds. Tedious and time consuming but genuinely gets you to learn their product. But once again, super time consuming. Prep aside, the entire thing stretched for over a month

Interview
It was well paced but I was not expecting as many questions as were asked on the recruiter call itself, it made me question how much more would be asked in the next 5-6 rounds
