HR reached me pretty fast and offered to schedule the first interview with someone from their engineering team. I was asked some basic questions regarding my previous career and skills. Then I have online code session where I should solve pretty straightforward tasks which I finished very fast. There were a couple of questions from interviewer, something like what would you change in your code if you have more time, or how would you rename variable names to make them sound less general, but nothing serious. In two days I got a rejection without any explanation. Based on the previous almost similar experience all this seems like a waste of time.
