Sherpa 6 interview questions

They reached out to me. I had a quick phone call with one person. Then took a test. Was told over email I did well on the test. Days past after that without anything. I sent two follow up emails. Never heard back. After silence for about a week did a bit more research. Research revealed that most people on the website in executive roles didn't exist, no social profiles at all. So now I start to think what is the point of setting up a fake company like this. I mean it all looks real. Then I look back to the test. I have taken several tests on multiple platforms but never had taken a test on the platform they used. Are people really creating fake companies to trick developers, whoever to test and train their software. Perhaps?
