At first, there was a call with one of the recruiters. They then set up a face-to-face interview with a senior developer for about 30 minutes, which was pretty straightforward.

Later, I was asked to attend the Tech Night in November. It was a two-day event, and interviews were held on the second day.

The interview was about 30 minutes again and focused on my resume and interests. This was the case with almost all the interviews.

Later, I was told that there wasn't a role for me to fit. The recruiter didn't even give the reason for the rejection. It's not something you expect from an HR-based company.
