This is probably very dated, but when I worked in biotech the interview process was just about 100% trying to find a "culture fit" (to be fair, in an industry about a thousand times more diverse than software) and politics. If the hiring manager brought someone in then you assumed it was on them to have screened for competence, and you wanted to figure out which candidate you'd like to work with, and/or figure out which candidate was favored by which person in power so you could vote advantageously.
