In the interview they have most covered basic concepts of React and javascript and a couple of programming questions. In terms of difficult I would rate it as Medium. Overall interview process is good.

Muito boa, sem pressa, foi na verdade uma conversa amigável. Me deixaram muito tranquilo para falar tudo o que eu tive a dizer. Sem muitas perguntas. Bate papo bem rápido.
