There were 2 rounds, first was a typical HR round with basic information exchange.

Second interview was a technical interview with 2 senior developers. They introduced the team and the project briefly, then asked me to tell them about my biggest challenge I have ever faced as a developer. During the interview I did not get further questions about myself or my experiences which was interesting. Next they showed me a really complex Java class and asked me to review it as if it was a code review. I did not get any further instructions and I needed to provide them my answer immediately. Then I needed to solve a couple of live-coding tasks (some recursive algorithms, some Big O related improvements, etc). They told me that they wanted to do some system design practice too but it was too obvious that I am not a good fit for the team since they wanted someone with bigger and better experience so we did not even get to this point.

Overall the interview questions were not difficult but the way they were presented made me really anxious because of the lack of thinking time and constant talking. They expected to provide the solutions almost immediately. When I stopped to think for a while they started to talk about a possible solution so I had to go along with their thinking instead of coming up with my solution. If I got these questions and tasks to solve them alone in 15 minutes, I could literally solve them without a single mistake, but unfortunately my attention was focused 95% on the situation and the interviewers that made me very anxious during the interview. After the interview I realized that it was kind of a stress-interview and they purposely tested my ability to work under very high stress.

The assessment included basic data structure and algorithm related coding exercises.
