See it for what it is: a red flag. Recently I had one where I had a feeling but threw it to the side because I thought I would give the person the benefit of the doubt. But then in email correspondence with who would have been my team lead or project manager/owner it became crystal clear that this person's personality and mine would not work. It also illuminated a lack of professionalism as well.

I have been in this industry 10 years now. I am not a million dollar a year 10x engineer but I have taken jobs that paid well but that were horrible environmentally and know now that if I feel ominous things in just the interview then that's all I need to know to avoid a potentially toxic workplace.
