empowr Android Engineer interview questions

They called and told me to make an app. After submitting the app, never heard from them again. It's probably a good thing because based on their reviews, this seems like a crappy company anyways. Applied so I can get some interview practices, even then, not worth the time. Just talking to the recruiter and they have no idea how they're making revenue by having the app or website that's similar to facebook. As an user, you can like/comment/share something and you get money. Too good to be true. Probably some kind of scam.
