Applied on their site. The recruiter reached out the next week and scheduled an interview, which mentioned it would be a live coding round. Though it wasn't, and the interviewer actually asked simple questions, I fumbled badly.

First call to describe the role and some technical questions about the past projects Second call, coding interview where you're left alone and when you have questions nobody is looking at you or hearing you out, weird. Third call: System design interview, there were a lot of questions and replies and it was interesting.
