I'm not sure if I'm following the same train of thought as
@hishedale , but the audition is a cattle call.
AUDITION ADVICE
Make a cheat sheet with your correct clothing sizes (including hat). It'll help fill out your info sheet.
They'll take a photo of you if you don't have a headshot.
An extensive resume is not required.
They'll ask you one or two questions. It's always better to think a little different from the pack. If they ask for your favorite scary movie and everyone is saying, "Elm Street, say "13 Ghosts" or "Let the Right One In." (Don't say Showgirls- they've heard the joke.) If they ask for your favorite HHN icon, when everyone says Jack, say Fear.
Be honest, friendly and upbeat. Look like someone who wants to be a part of the team and you up your chances.
Back to spec. I dig that last clue series with Mamba. The lines are drawn, it looks like.
