The CTO contacted me via LinkedIn and she scheduled an interview. We had a typical interview and after that I solved a test with the cam opened so I could not cheat. I did well on test and she asked me to fill a curriculum in their template so she could present me well for the client, which I did. After that she ghosted me and only after almost two weeks she answered that their client changed their mind. It seems that they do not have the vacancy. It seems that they first try to see if they find someone good enough to then, try to sell them to one of their clients. I would not recommend this consultancy if you do not want to lose your time.
