Although I have very little hiring experience, I thought it best to eschew typical interview questions like "What is your greatest weakness?" and "Don't you think the sweater I'm wearing perfectly accentuates my chiseled pectoral muscles?" in favor of a casual conversation.
Me (crying): "…and then she hit me in the stomach and my retainer fell out of my mouth and into a mud puddle."
Candidate #4: "And how did that make you feel?"
Me (sobbing): "Weak and dirty."
Candidate #4: "I'm sorry to hear that."
Candidate #4: "So, are you going to hire me or what?"
Me (disgusted): "Ugh. You are so unprofessional."
Needless to say, based on the ever-so-slightly embellished exchange above, the reasoning behind conducting a professional interview as opposed to attempting to become best friends with each and every candidate is now readily apparent to me.
