Shake hands with the interviewer and exchange pleasantries. Try to invest some feeling into the handshake and pleasantries, even if you think you bombed the interview. The interviewer should give you a time frame for when to expect to get a callback, if applicable.
• Hold your head high and keep your cool. Your emotions are probably teetering at the highest of highs or the lowest of lows, but try to stay measured. Project a cool confidence — not cockiness — and walk out of the interview with your head held high.
• If the interviewer does not tell you when they will contact you if you're a good fit for the position, it's appropriate to ask, "When can I expect to hear back from you about the position?" This will prove important later on.
