You can have an entirely different skill set, knowledge base, experience base, and be a similar fit, culturally.
But you know, if you have an office full of people who enjoy spending their time together, who play games together after work, who go to lunch and laugh and talk, who listen to music out loud and don't prefer to have a library-quiet office space, then hiring someone who prefers to be a loner, who doesnt play well with others, who is arrogant, who needs absolute silence to work... those are pain points.
Culture and skills/experience are not at all related.
I think you've fallen into the trap of confusing the people with whom you work and the people with whom you are friends. There is zero need for those two groups to overlap, and it's really only in the tech world where the "culture fit" phenomenon is trying to force them together, often to try and get employees to work longer for free.
There is no reason that your friends and co-workers shouldnt overlap. There is no reason you shouldn't love going to work. There is no reason you shouldn't be happy in the company of the people you're around the majority of your day.
Your very post, is just you applying your own culture to a job. Part of your culture in the workplace is a detachment. Thats ok, everyone has their own thing, but you wouldn't fit into a place where people want to be inclusive, you would stand out and probably be considered an asshole by others.
You see that your view on what should happen in a workplace is very different than mine. That would cause strife over time, it would reduce our ability to work together compared to people who shared our viewpoint... While your view is equally as valid as mine, and neither are more correct than the other, they are definitely different.
Recognizing that difference is what the culture fit is all about.
And your last line, comes of as purely cynical. I don't work longer for free because i like my coworkers... I still work the same regardless, but I tend to LIKE going to work more, and enjoy my time, and feel more invested in the company when I enjoy my coworkers and share a bond with them...
Being friends/social with coworkers should be an opt-in experience, not mandatory for your employees. People have lives.
There is no reason you shouldn't be happy in the
company of the people you're around the majority
of your day.
If work=life is the only way to fit into your office, it had better be doing something life changing to justify that demand from your employees. Otherwise, you're stealing their precious time. The one thing we can never get back.
My "culture" as you put it is really an anti-culture, and it's the one that has worked for hundreds of years in workplaces around the world. I don't care whom I work with so long as they are professional, capable, and skilled in the tasks they need to do on a regular basis. What they wear, what their hobbies are, whether I enjoy talking to them about non-work activities, etc. has basically zero bearing on my evaluation of them as coworkers. In a very real sense, that approach is more open-minded and inclusive than yours, which prioritizes specific personal traits rather than job fit. That's the whole point of the post we are discussing in the first place - imposing a "culture fit" on a workplace to the exclusion of perfectly qualified people just doesn't make much sense. You might claim that employee retention and productivity are higher with a tight "culture" (though I would be extremely skeptical about that claim), but at what cost does that come? Or how about this - how well would the Apollo program have worked if NASA insisted that every engineer, astronaut, and flight controller had to be friends? If you want the best of the best, you deal with personal differences and still accomplish great things.
My last line is indeed cynical because it comes from the perspective of having been around the block a few times when it comes to companies supporting employees vs. supporting bottom lines. I've also seen how paragons of "strong culture" fall apart once employees get out of their 20s and start to have a family and social life compete with work. I really do hope that you're able to continue working with people you enjoy hanging out with every day, but unfortunately real life tends to make that difficult over time.
