the way they pick survivor contestants

i love the show survivor. i also am baffled by the people that end up on the show. i can only assume the way they choose contestants is according to this type of questionnaire.

Survivor Host : Hello
Potential contestant : O Hi there.
Host : So tell me about yourself.
Contestant : Well, I'm -
Host : (cuts them off) - are you emotionally stable?
Contestant : Well, i have had many emotional traumas in the past year that were personally devastating.
Host : Perfect.
Contestant : Um.
Host : Are you willing to say outlandishly mean and potentially incorrect things about people you just met?
Contestant : You mean like you? You are such an INSENSITIVE JERK.
Host : (to himself) yes.
Contestant : What was that?
Host : I dont think you are ready to be on survivor
Contestant : OK. I will fake like i have hatred towards numerous people groups and / or people with disabilities.
Host : Thats not enough.
Contestant : Ok, I will also call everyone else on the show shallow names like ugly, stupid and dumb, on camera for you to use as you please.
Host : I would also appreciate it if you punch Jeff Probst in the face.
Contestant : Sounds fun, but i wont make any promises.
