I can point out that this company is the worst one I have ever interviewed with. A quick note: I had two steps, first with HR, and the second one with the manager of software engineering or something similar. In both stages, I asked them to give me detailed feedback if possible in any case of rejection. The result is they disappeared; I did not even get one short message that I was rejected. The second point I wanted to call out is that they are suggesting a salary that is two times less than the market rate. So, I think it would be better not to spend any time on this kind of company. I was interviewed for the iOS developer position in Warsaw, Poland.
