I think it would be extremely counterproductive for a company to filter on extroverted people for most positions. Maybe it barely makes sense for a startup sales or PR to be extroverted because you kind of expect them to bring in connections from their (hopefully vast) personal network, but for the vast majority of positions I think you'd be looking at false signals and missing out on some extremely capable, focused people by blocking out introverts from your search.

Introverts are VERY GOOD at getting shit done. Introverts aren't opposed to teamwork and collaboration, it just means that when we get off work, we usually chill alone or occasionally with 1-2 close friends, instead of partying.
