I applied for a Python position with the Polish team. There were 2 interviews and one meeting for a GitHub challenge. The first interview was with a recruiter, who explained everything to me in detail about the company and role, answered my questions, and promised to get back in 2 days. Already the next day I got a challenge that I had 1 week to work on. After that, there was a challenge discussion with the tech team. Everyone was professional and friendly, recruiter was the best. Did not get the offer though, will apply next year again;)
