This makes some sense, I've met or worked with easily 100 MIT grads, all of these failure modes feel within the band of the kinds of issues you have. The people who are duds on a purely productive level definitely fit the mold you describe and tend to burn out in low end jobs from what I've seen.

The attitude problems are common enough that managers used to recruiting out of these schools learn strategies specifically for handling them. I've regularly heard comments like "So-and-so is great but they're very green and just... very MIT" and everyone knowingly nods their head and commiserates. Things usually get better once they've been out of school for 4-5 years (though also, some are great straight out of school).

Graduates with none of these problems generally get snapped up by super prestigious positions so you're less likely to interview or hire them if that's not you.
