They will throw the API on you via email without any documentation or explanation of use or examples. I had to figure the API endpoints myself by debugging their website remotely using local proxy (Burpsuite) to understand each endpoint functionality.
They ask you with the API they provide you via email to come up with some idea or small demo project to prove for them your skills.
Even if you got accepted or not they will literally steal your idea or features from your demo project to be added to their platform and this literally what happen to me personally. I do not recommend anyone to apply to this scam company.
