I applied online, I had 5 rounds in total, initial was a recruiter call, followed by tech lead, then a senior engineer, then Director and finally another tech lead. The interviews are a mix of coding, general broad technical knowledge about various aspects and a system design. The interviews were scheduled very fast and feedback was shared immediately on the same day. I got the offer 2 weeks from the final round which is normal for Xsolla.

Very slow moving - It took two weeks just to get to the second interview to tell me there's three more to be scheduled. Other companies were chomping at the bit - therefore I chose to not move forward with their 1-2/mo long interview process.
