There were two stages of the interview.
First was an IQ test and an English language test (they just loaded up websites and handed us the laptop), and they instantly rejected anyone with an IQ lower than a threshold (I dont remember the exact threshold but i think it was 100)
after that was a one - on -one interview with either the product manager or the COO, I got the former. he asked questions about react and javascript mainly, not really delving into other areas (although he didn't ask too much if you didn't have experience with these two)
Interview process overall was very mismanaged and had to wait multiple hours for my turn.
