Getting a job in a Smithsonian museum is like getting a job in academia. It’s absolutely impossible because you have to wait for someone to die for a position to be vacated.

Museum jobs like that are the crème de la crème for folks in that field, and between the reality that there are so few of them, and that people keep them for life once they have them, it’s unlikely your friend will ever get one because when they come available every person who ever graduated in Museum studies anywhere in the world is applying for it.
