It seems this post wasn't that well received, so let me just go ahead and mention as a follow-up that I was once an "angsty college grad" myself. There was a time I contemplated and almost convinced myself that there might be something to this "cultural fit" thing. But then I experienced the work force for an extended period only to realize my preconceived notions of what it takes to be successful in business has almost nothing to do with personal traits. In probably every way I've ever thought about / experienced it, successful businesses are built by people whose workplace behaviors are composed of UNIVERSAL traits.

So, it follows that, for someone to say you're not a "cultural fit" more or less means you don't have what it takes to truly be successful no matter who hires you.
