Job hunting is hard enough.
Don't do it alone.

A guild isn't a group chat. It's a small team with a shared weekly quest — and a live feed that makes it impossible to disappear without someone noticing.

Up to 6 members — small enough that everyone knows each other's progress
Weekly guild quest resets every Monday — shared goal, shared accountability
