Of course, I can only react to what I read. If it doesn't make sense without parts that are not present or without parts which don't exist yet, then...I don't feel like that's my responsibility? :v *pointing finger slowly at ya'*
Being hired! into a position like that through a "job application process" is, omg, how to put this nicely... - I'm sorry, I'm known to be blunt. - Uh, nonsense? Unrealistic and opposing everything one may or may not know about the dynamics of power, control and frankly just humans in general. I'm rather surprised you're trying to defend it at all - it wouldn't happen in the most meritocratic of made up societies. Because people are still people and politics is still politics.
ROYAL. ADVISOR. Consider these words for a minute. You think sb. is being "hired" to be an advisor/whatever of Charles III?
Yea, exactly. And he's not even from a medieval/-ish society.
You'd need to be chosen. Hand picked. And you'd have many competent competitors for such a coveted position. (Once upon a time, the Conservative Party opened their arms wide for candidates who never participated in politics before. They got 4000 applicants. And in the end, 4 were chosen. Who were, ultimately, very much like the career politicians they already had...)
You would need real, not made up connections in high-society, years of advisory experience, immense trust from at least part of the court and at least one of the royals already. You'd need to be present for a substantial amount of time before all this. You'd never get in as an outsider, never! It's like trying for the top of academia without any formal education. Come on, man.
Look, at the end of the day, this is not my circus, not my monkeys. But I do recognize a hot mess when I see one and I'd rather not waste my time on messy drafts :v
Edit: Remembered the wrong party and higher numbers, but still
One last thing: write what you know
