I honestly think it was a scam. They were very responsive at first and then when I sent them a project, like basically free work, heard nothing from them. It was all very weird with just like 10 employees in LinkedIn. It was for joining their 'AI First' team. Had an initial interview, and then instead of having two more interviews, they jumped me into the final step which was a test case to create a complete POC for an app in just three days, relying in AI tools for it. I delivered a great app with a brand and all, investing as much time as possible in it. But then when I send it I didn't got any answer, like not even yeah we're reviewing or nothing.
