First there is an interview with the recruiter talking about the company and your experience to see if you match with the profile they are looking for.
Then a coffee chat with 2 engineers to talk more about the role and so on.
They send you a task to do in one week and once you deliver it you have another interview to review your exercise. They ask you questions about your code and also so many questions about java.
After this interview they sent me an email saying that I passed the interview but that they thought that not at the level they wanted so they offered me lower conditions and I rejected that proposal

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.

Interview
The interview was correct, rather it was an interview of attitude, way of resolution, vision.
