It tends to happen alot for me in VII and VIII. I'll be at the end of disc one and realize my whole party is 60+ in levels and the amusing thing is that I don't even grind in this game like I do in other FF titles so it always catches me off guard that I'm usually over-leveled.

VIII makes a bit more sense because the game is designed for the player to level faster than normal, its having low levels that actually requires a bit of effort.

The only other FF where I've maxed out levels is the DS versions of FFIII and IV. III cause I'm trying to get maxed out HP and IV because it seriously takes that long to get some of the games rare drops.

I think the only FFs where I tend to always be underleveled is always FFV and XII (technically XI but that's another problem all together) mostly cause levels don't carry the same weight as they use to in these titles and getting rare drops is either easier or I simply don't care.

EDITIGA: FFTactics is another title, I tend to enjoy maxing out job classes before moving on so my party tends to be a bit high level for the story battles.
