Here you can find all the quests that you may not have received during the Main Questline for The Companions. Or, maybe you’ll find some that you aquired that weren’t in the main guide. They are Radiant Quests and can be done time and time again. Either way, we got all your needs right here!
Note: Many of these quests are given by following The Companions Miscellaneous Quest "Talk to the Companions leaders for work". As many of these are Radiant Quests, the game will give you different objectives than it gave me. Knowing that, use my advice as more of a guideline than anything.
