Tribalism works. Most job openings are not advertised but are filled in with tribe members related to an existing employee.<p>Many things can be called a 'Tribe' - alumni networks, friends-of-friends, same city, extended family, and on a larger scale, caste, nation, religion, earth (if you are visiting other galaxies).<p>Nobody wants to credit their success to tribalism but it is a very dominant force in our lives. You need to be the right circles. Keep good company as they say.<p>... Or you can conveniently blame your fate on nepotism.
