I don't feel like that's the best approach - there's no real point to being max level before you get to the end of the game. It's more useful to keep your main job roughly equal with the MSQ so you can continue to earn EXP from quests throughout the game. (I'd suggest "two levels above current MSQ quest level" as a good balance - you'll never get caught out by the quest level going up and locking you out of continuing the story.)

It's also fairly easy to raise two classes at once, especially if you like to do all the side content - I was leveling summoner and white mage equally throughout Stormblood, using summoner for story progression and white mage to run daily roulettes.

You get a nice exp bonus for your second job if your first job is maxed...
