What if the interviewer is smokin' hot?
Don't appendix carry. haha
To quote George Clooney from Oceans 11..."you want to be likeable, but not memorable"...or something like that.
When I conduct interviews, I look for character over qualifications. Most people have the mental capacity to be taught at least somethings. Not everybody wants to be taught anything. Don't be afraid to laugh or tell a compelling story that really illustrates who you are.
Of course, if you tell a story and don't get hired...not my fault. lol
