I applied online. The process took 4 weeks. I interviewed at Celonis (Prishtine) in May 2025
Interview
The interview process is divided into 3 stages after the initial one with recruitment specialist. The coffee chat with the team lead, where I had the chance to know more about the team and describe my experience, I liked the fact that the team lead went beyond the allocated time to answer my questions.
The tech challenge was quite stimulating and I think it gave me a good perspective into the expectations for the role. I did not find any surprise questions here, which is good, the tech interview was solely based on Angular topics but some very important language-agnostic ones as well.
The last interview was with the VP, there were some interesting questions asked about my approach on how I make UI-related decisions.
