I applied through a recruiter. The process took 2 months. I interviewed at Celonis in Jan 2023
Interview
For me, the interview process was spread over about a 2 month window where I interviewed with a few groups of people including teammates, other developers, and management. Probably the key difference between my interview experience vs other locations is that Celonis did not have a "stump the chump" part of the interview. Instead, that was replaced with the interviewee putting together a 20min presentation to give on any tech topic of their choice.
Interview questions [1]
Question 1
I got some straight forward questions on technologies like rabbitmq, kafka, eks, and aws. These were mainly around what my experience with these things are or if I have used similar technologies in other roles. There were also some questions on process, like google SRE best practices, chaos testing, and SLOs. Most questions I had were more experiential questions asking about personal experience. This made for a friendly interaction and everyone on the interview panel seemed interested in hearing the answers.
I applied through an employee referral. I interviewed at Celonis in Jul 2024
Interview
I got 2 technical rounds, one is more about production incident management and one was about Java. I also had an introduction interview with a hiring manager who described me a scope of work I suppose to do and behavioral interview with a manager of the division. The distance between interviews was few days and the whole process was pretty straight forward
