Look around, everyone is smart. Smart is now the minimum. Everyone has a college degree. Everyone tested well. That’s what got you in the door. Smart is how you even got to the table.
Are you tough? What are you willing to do that other people won’t?
Are you capable? What have you executed?
Are you reliable? What have you managed?
Are you interesting? What have you created?
Even if the questions aren’t being asked aloud, they’re definitely being asked subconsciously.
Have the answers to these things. Don’t take up anyone’s time until you do.
