Proxify interview questions

I found them by using google, and decided to apply. An Argentinian talent seeker (very nice person) approached me and we agreed on having an interview, after the 1st interaction I was sent a Codelity test with 3 questions, got 2 of them with 100% coverage with C# and the last one with at least 60% which I thought was enough, it has been more than a week without any news from them. Been ghosted since them, tried to add the recruiter on Linkedin.. nothing. Sent 2 emails, but nothing. All out of nowhere, no feedback or anything. I do not recommend it, spent 3h of my life for nothing, I guess that's what you get when you go into crazy companies that rely on code tests from Hackerhank, codelity etc.
