That's not quite correct.

Sometimes, the NPC that gives you the job quest is not the guild leader, but rather the receptionist. That's the case for monk, paladin, scholar and black mage. The person might simply not have noticed the quest popped up and thought he was done, since the guild leader didn't have anything left for him and that's where he expected further advancement, especially since you usually get the message:"The next Class quest becomes available from NPC at level YY". None such thing happens at 30 if I recall correctly.

Besides, even if he "did" notice the quest, he might be oblivious to the importance of jobs and thought he could just do that whenever. It's not like the game tells you every five levels:"You just missed out on another skill, sucker!"
