My comment was mostly in regards to the snobbiness of the "top tier" aspect. The person is free to explain his decision to leaving a job of course, but the bragging is just sad.

I think that's fair. Either way people don't need to be so unnecessarily harsh. It was pretty clear OP didn't intend anything particularly harmful. It was probably just naivety or a lack of self-awareness...but people are talking in here about it as if it were pure evil.
