Concept that comes from RPG's, or any sufficiently complex optimization problem where you have a limited number of total points to spend so you "min"-imize the least helpful stats and "max"-imize the most helpful. For a fighter character, you'd obviously max out strength, as well as constitution and dexterity. You'd minimize intelligence, charisma, and wisdom - not because they’re not helpful but because you only have a limited number of points to spend. In the context of:

> The trick to effective min-maxing in social contexts is to make sure people can't tell you're min-maxing.

It means that, while in interview situations there is an expectation that you say "I did this", in social situations you might get more benefit from seeming to be more humble and appear to withhold your accomplishments, perhaps doing it in a way where someone else fills the gaps for you, or it entices the other parties into doing a bit of digging on their own and perhaps find some well-placed bios online that look like they weren't written by you / at your behest which do your bragging for you.

This avoids the situation where someone will say: "I work on Copilot now, and I can say this guy is totally full of himself." as other people respond "huh. yeah. that makes sense."
