It was an initial screening with a recrouter. The second step was a test assignment, quite simple at first glance, but if you want to implement it to the best of your abilities it may take a while. The issue is that the company doesn't value your time. After completion I received feedback only weeks later that was telling me that the guys were not able to find some required parts in my codebase, but to me it sounds that they either didn't understand the complex solution or they didn't even make an attempt to do that.
