5. Be Energetic

Interviewers, whether they are from HR or from the actual department you’ll be working, want to recruit people who are energetic. Imagine for yourself: Would you rather have someone who is always on the go or someone who looks sleepy allthe time? In addition, if a person does not show much energy during the interview, the interviewer will think, “Geez, if this person cannot get excited about an interview, how is he or she ever going to be excited about the job?”
There is one area where being energetic really pays off: Many interviewers start with the question, “Tell me about yourself.” If you cannot enthusiastically talk about yourself for at least five minutes or so, the interviewer will wonder if you’ll be interested in your future job for much longer.
