There were three interview steps: 1. On-line programming test consisting of 9 programming tasks (you don't have to solve them all) 2. General interview with software engineer (with some trite logical task as finding a wrong ball among 9) 3. Technical interview with software engineer. Here they try to understand your knowledge about the domain they are interested in in a form of discussion.

I was contacted by the recruiter, had a call with the person. During that call, I was asked about my experience and they told me about the company and the role I was contacted for. After the call, they send me a takeaway (home) coding challenge. The problem I was asked to solve was simple but took me a while to work it out (I send a day on it). After completing the challenge I submitted the code and it's been more than a few months now have not received any feedback from them not even contacted back from them. I spend my whole day working on the problem they could have at least sent me an automatic rejection email or something. I would recommend staying away from this company complete waste of time.
