This point was cited in a recent article I think debated here (or Reddit), "This is why you never end up hiring good developers." You push away a lot of talent when you select for some narrow culture fit, or mandate that they be your friend too.

IMO, the obsession with culture fit and team bonding is really just a way to trick engineers into devoting more of their life, mindshare, and personal freedom to laboring for your startup.

In some countries (the UK is one), you need to be very careful with "cultural fit".

For instance, not hiring someone because they don't want to go for beers on a Friday can accidentally become a proxy for excluding certain religions at which point you can be in all sorts of bother legally.
