I feel bad now. Even though I would never talk like this I can't help but feel this way sometimes at my current job. I feel like I am genuinely asked to do retarded shit sometimes, and no one else seems to mind.
I would suggest that if you feel this way for more than a couple of months then perhaps you should look at finding another place to work. Being smart doesn't make you an asshole. Just don't bad mouth your previous colleagues.
If someone I interview is to say that they "grew beyond the technical capabilities of the role and the company was unable to support further growth of my skill set due to the direction the business was going" then I am cool with that. It happens. Hell it SHOULD happen. You should out grow your old position if you want to move up. It is all in the way you not only say it but how you BELIEVE it too. If you just say something like the sentence I wrote above but really believe that you are some "rock star" and everyone else is an idiot then I am probably gonna pick up on it even if you phrase it in a nicer way.
I have had people in interviews confess to me that they are (1) subordinate to their spouse, (2) very concerned about personal safety in a big city, and (3) afraid of scorpions. These are OK things for those people to feel, but to bring them up in an interview does not improve their chances.
