Just a fake content creation collection free of cost - Educator bei Create and Learn: Mitarbeiterbewertung

I was contacted for anEnglish curriculum development position.I was assigned a task .The HR was promptly replying to my mails before getting the task done .But as soon as competed the task the company vanished .No response either from HR or the Founder member.I am just asking for feedback on my work that also they are not able to provide.This makes me think this was just a content collection exercise by the company for free.
