Perguntas de entrevista de vagas de Junior Java Developer da empresa Classboxes

The interview was very easy, but on looking in to this company I suspect this is a scam. There's a lot of posts on Reddit describing how this company scams applicants. They fail to find you work, then expect you to pay them a share of your salary when you find a job without them (it's in the contract). They also allegedly charge some people for their training. I strongly suspect all other reviews on their page are sockpuppets: all 5 stars and they all say nothing of substance. They've been seen using fake accounts to astroturf negative Reddit posts, so it's hardly a stretch. Needless to say, I'm not going to move forward with the interview process.
