Another is baiting people into "pairing" if they aren't going fast enough or operating with enough velocity. This generally entails just giving someone the solution, prevents them from learning and also generally feels demoting. The weirdest red flag I've encountered is a prior employer that got mad and though I was "misdirected" when I was digging into their code and looking into problems slightly outside of the tickets they gave me. Their later comments were, "we wish you'd spend more time finding extraneous wins outside of your tickets"... I willingly left about a week later.
