In order to land a job like this, you'll need to polish your interviewing skills. Be prepared to answer the most common interview questions and also a few curveballs.
For an interview like this, you'll want to dress formally. Best-selling management author and CNBC contributor Suzy Welch says that dressing too casually can sabotage your chances — especially true when you're applying to join the queen's staff.
When in doubt, it's always better to be overdressed than underdressed, says Welch. "Look, these days, it's perfectly OK to show up in jeans and a T-shirt if, and only if, you're interviewing for a tech company with three employees who think hoodies are formal wear," she tells CNBC Make It.
Before you leave, Welch says that applicants should stress how passionate they are for the role by simply saying, "I really want this job."
"Make your case. Give it your all," Welch says. "And somewhere near the end of the process, make sure they know how you really feel."
