As someone who's travelled 10,000 mile round-trips for final interviews, only to lose out on "culture fit," I find it the most frustrating excuse for not getting a job I have otherwise proven over previous interview rounds that I am capable for. Why? Because it's totally unquantifiable and subjective. Fair enough if you find a hole in my technical ability which would limit my performance in the job you want me to do, but using "culture" as the excuse is a nonsense.

There could be any number of reasons someone might not appear to "fit" on a given interview day, which wouldn't necessarily apply in them in the day-to-day - jet lag, the stress of the interview process, being under the weather and many more...

People and cultures adapt over time, through contact with each other; if you're denying good candidates because of their "fit" in the now, you're artificially limiting yourself for the future.
