No. I am assuming that higher number = worse rank. No clue how you got the opposite impression. And mc has a poor rank, because it is high.
So either they want to hire lower-ranked ppl for their higher competence (most likely), in which case mc doesn't apply and them seeking her is an exception. Or higher-ranked ppl for their lack of allegiances and to up the average of the entire organization (very unlikely, but still a possibility), in which case the dialog is meant to imply that they are going by the rules/tradition.
Like I said, this is an extremely common error ppl often do, where they call the top-rankers as "high-ranked" (and vice versa). The words "top", "better", etc, and "high" are all similar words, but there is a clear difference when it comes to the ordering of integers, where "high" means something distinctly different from the others. That, in addition to how ppl generally associate the rank to someone's social standing (which is correct to call "higher"), makes this error
No, it is correct to refer her social/hierarchical standing as low, but what they are saying is that her rank (8) is low instead.
