I applied through a recruiter. The process took 3 weeks. I interviewed at Celonis (San Jose, CA) in Aug 2025
Interview
Two words - STAY AWAY!!!!!!!!!
I spoke with the Hiring Manager. Then radio silence for 2 weeks. Got asked for an urgent interview with some dumb head Eng lead. They responded 10 days after. The next round was supposed to be virtual on-site, but all the Europe people were on vacation. Finally, someone interviewed me from their vacation home and this was scheduled at 7 AM my (pacific] time. Then never heard back.
Interview questions [1]
Question 1
Some recommendation system design. Pretty basic.
Absolutely no structure for that on-site interview. They were shooting from the hip.
