7 or 8 rounds of interviews, each on different days, should have asked for the pay range before starting the interview process, it took more than two months and lots of interviews for them to not offer a position, disrespectful to candidate's time and effort

The interview happened over 4 rounds, and spanned over 8-10 weeks. Involved talking about your research, giving a presentation on your work, and talking about some future directions that you are interested in.
