Getting the job requires a good attitude at interview…
Use eye contact. Right or wrong, lack of eye contact communicates lack of interest, and lack of confidence. Make sure that you’re engaged in the interview process by maintaining eye contact.
Communicate with energy. During my years of recruiting I have occasionally come across candidates who appeared like they had one foot in the grave and didn’t care much about anything. Guess what? These candidates did not get the job. Be enthusiastic but do not overdo it!
Express interest in the position. If you want the job, tell the interviewer that you’re interested? People, who don’t ask, frequently don’t get.
Treat the interviewer with respect and act like he/she is the only person in the world. Focus your attention completely on the interviewer and your chances improve. Look away, or slouch, and your job chances will slide away. These actions indicate lack of respect and remember-you’re not having a casual chat with your friends-this is serious and potentially life-changing. I’ve heard about many candidates who lost job opportunities because they used slang or swore during their interviews so take heed.
Finally, after you have been offered maintain a professional demeanour at all times as job offers can be retracted if the hirer witnesses a change in character.
