Two rounds of interviews. The researchers and research director were really nice. I rate this experience as negative because of the company's HR who didn't come back with an answer on the day of the interview (as they promised) and ghosted me after a follow-up email. So after 2 rounds of interviews, a task and a follow-up email I got nothing: no answer, no feedback, no simple 'sorry, we thought you are not a good fit for this position'. They did ask candidates to do a task and to send them presentation materials (powerpoint or excel) for feedback. Why bother if you ghost candidates anyway? Really sad to see how a non-profit company that prides itself on hiring diverse staff couldn't even be bothered to respect their candidates and not ghost them. Wouldn't recommend applying there.
