My thoughts exactly. Nobody’s fully entitled to a job they’re indisputably the best candidate for (see Trump.) Sheer stupidity is not a crime, even for an employer. They are free to make the mistake of not hiring the best person for the job, even if it is just for the reason that the person is not very suitable for non-work activities of the company. They are free to consider a strictly effective work morale a con even if it would be generally considered a great boon.
Barbecue and ping pong tests really shouldn’t be the way to discover these incompatibilities with the existing workforce though and does sound super discriminatory and borderline illegal at the best of times. But if you emanate an aura of “Really wish anyone slacking off ever would get fired and will complain anytime something isn’t up to some idealistic guideline” in a, say, Valve-like work environment, then you should not be picked for some technical advantage you have on another, otherwise much more compatible candidate.
