Seems to be an agency, they ask you a few questions (how many years of experience with X,Y,Z etc., what is your availability and desired salary), no real info about their team. If they contract you, they offer a stable salary even if you don't have work (but seems like the chances are slim). Interview was done in 20 minutes, no classic "tell me about a time.." or "strenghts/weaknesses" questions.

Questions related to React's functionalities. First, questions about you professional background and then technical questions. It's important to clearly explain your answers and be on time for the interview. Work in your english skills because it could be required.
