The interview was in 2 parts one before the other: a) Technical chat (30mins) b) Live-coding test (1.30 hours) The interviewer was very kind and professional but the questions were a bit too JS theoritical. So if you apply for a similar role make sure you go and memorize JS/React interview questions and you should be fine. They won't test your development skills, but your ability to remember terminology of stuff that you are probably using every day in various complex forms but are not aware of.
In general the interview was in the very easy/easy spectrum, but I felt very alienated when the process stopped by the interviewer before the live-coding part, because I didn't remember the correct terminology from the first year of University of Javascript. I've been hiring developers for my team in previous roles and the above process was not just unfair but weird.
