Jobs need 100 exp to level up. But this EXP is different from EXP after battle. UEvery action gives a certain amount of Job EXP. Until your class is level 14, every action gives 20 exp, so if you have every battle last for 5 rounds, and every person do something, you will gain a job level every battle up til level 14. The easiest way to do this is to guard. Guard for a few turns, then kill the enemy. After that your battle EXP depends on what job you are. Each hand has EXP and levels too, and just using it raises it, but I see no way to actually see the values or know how high you've trained a hand.
