> willing to basically do whatever I want him to do whenever and however long I want him to do it. In other words he’d be a good lackey.

This is unnecessarily condescending. When having to choose from a crowded field of seemingly-competent candidates, it's natural to want someone who is passionate and willing to go the extra mile. And as someone who is genuinely passionate to work in a certain industry or to work for a specific company, it is also smart to signal your dedication using tactics like what the author described.

Neither of the above warrants condescending to someone as "being a good lackey"
