The first red flag was when HR was replying to my emails basically at midnight. The interview process was overall unpleasant, during one of the interviews I was asked to repeat what I said because they needed to "write a report about the interview". After the second interview it was crystal clear that company culture is toxic and it is better to stay away from it. After the last interview HR ghosted me for a few months just to write one day a line saying that they would like to interview me again. Avoid this company at all costs, don't even waste your time on interviews.
