If im not wrong,

lv 60 clerics get the "Supportive Paladin" title, after job change they get the "Paladin" class

lv 60 fighters get the "Tanker Warrior" title, after job change they get the "Warrior" class

lv 60 archers get the "Rapid Scout" title, after job change they get the "Scout" class

lv 60 mages get the "Powerful Enchanter" title, after job change they get the "Enchanter" class

so basically u get a title when u reach the appropriate level, even before u change class, but u still need to do the job change quest if u want to change class. Note that there is a difference between titles and classes.
