I became intrigued by the company at a big data meetup, which was held alongside a recruitment event in Budapest, Hungary. At the meetup, I met a recruiter who came from the same company I was working for. We chatted for a while, and as the hiring event was still ongoing (with many interviewers available), I was scheduled for multiple interview rounds the following Monday.

The interview process was quite smooth. I was received by a recruiter who escorted me into a small office, where I stayed for the entire process. There were four interview rounds, each lasting 45 minutes with a 15-minute break in between. All rounds were conducted in English.

All interviewers made an effort to ensure the interview was a pleasant experience, trying to put me at ease. They asked their questions and discussed points in a supportive manner.

Staying in one place while the interviewers rotated was a nice experience. It's much easier on the candidate than being shuffled from room to room or deposited in hallways while the next interviewer arrives. Having refreshments available in the room was an additional nice touch.

The follow-up was also quite speedy. I received the first (positive) feedback in three or four days.

Describe an event from my (professional) past where I made a bad decision, including the root cause and the effect that this mistake had. Then, describe what I did to fix this mistake.
