One guy and one woman took turns asking questions, mostly about experience, and the man was understanding, but the woman was very condescending and seemed to be laughing at my extensive experience, saying it was all done for 'educational' purposes and not professional.

Well madam, if all the companies I worked for are not real, then you can make fun of my not real experience, but just because you work at a renowned company doesn't mean you can laugh at somebody whose heart is set on joining your company and has worked at less famous companies.

Neither was bothered to turn on their camera, and it seemed they were already set on not giving me an offer and trying to poke me into a negative reaction.

What is your experience with DB?
