You sail out of the interview, practically high on the unshakeable feeling that you absolutely nailed it. The interviewer was openly impressed with your experience, you didn’t stumble over your answer to the sometimes perplexing "why should we hire you for this position?" question, and you’re wearing a new get-the-job outfit to boot. You ship off your thank-you note with a smile on your face, and pounce on your phone every time it vibrates, hoping for an offer.
