If you ever have a manager who jokes about being a horrible manner with some weird sense of pride during an interview, don't take the job. I learned the hard way.
I left that job 2 years ago after ~8 months. Mentally fucked me up and it took a long time to recover from the ineptitude and incompetence in that company.
I looked at their glassdoor reviews and the same complaint and comments me & co-workers made when we left 2 years ago are still repeating with people who are joining and leaving today.
Never again going against my gut feeling.
