Earlier quoted context omitted.
My answer would be: why are you asking me? Shouldn't I be asking you? Do you have coding standards here? Or is it going to be my job to decide on the coding standards?
and you would have missed the point of the question entirely. Regardless, thats a pretty unnecessarily aggressive response to an interview question; or maybe I'm just reading it that way.
It's not meant to be aggressive, but to make a point. It's important that everybody uses the same coding style, regardless of personal preference. Spaces are fine, tabs are fine, but mixing them would be absolutely terrible. A programmer's personal preference for one or the other is irrelevant. What matters is that he's willing to adapt to the coding style of the company.
