When asked about their profession, a noble usually just states their title and their former labor profession. When pressed further, you might learn when the position holder took up the title, or how long they worked their labor profession beforehand, but that's about it. That isn't enough information to properly define a character on its own, and unless you go dig the noble up in legends mode, that's all you get.
It would help if position holders stated their responsibilities when asked about their profession. A sheriff or guard captain should make a point of letting everyone know they enforce the law, and a monarch isn't going to let an opportunity to remind people that they lead an entire civilization slip by. It would also make sense for them to talk about important events they took part in. Beast hunters already do that with the wild animals they kill, I imagine certain nobles would have something similar to say about their job. A general would brag about how how many kills they made in battle, a hammerer would mention a notable execution they performed, that sort of thing.
If they can tell you what they're supposed to do and what they've dealt with pertaining to their position, you've got a far better picture of who you're talking to than just knowing they are lord and were a fishery working for twenty two years of their life.
This would really shine with generated positions that sport less than straightforward titles. I would appreciate the fact that Olith von Importantguy is First Seasons a little more if he told me what a First Seasons does. I'd appreciate him even more if he told me he once did something cool, such as personally slaying a hundred enemies while he led an attack on a dark fortress.
But because a I have no immediate way of knowing how important a First Seasons is, and he has no way of telling me what he's done as First Seasons, he's just another flashing U to me, when for all I know he could actually be the most interesting person in the world.
