- Be prepared, they may want more
Make sure you can expand on all of your answers. Your resume may well provide them with all the info they need - but the interviewer needs to check out your communications skills. However, make sure the additions to your answers add value, don't be long winded for the sake of it. - Need to present? Practice what you're preaching
If you're asked to make a presentation keep the content short and simple. If you have been asked to present for 15 minutes, make sure you have not completed it in five, or that you're still talking after half an hour. Run through your talk a few times in front of the mirror - this will help you get your timing right. - Ask them questions; consider their answers
There comes a point in every interview when you'll be asked: 'Have you got any questions?' The worst answer you can give is no. Think hard about what aspects of the job are important to you. Are there training opportunities for example? What are the opportunities for career progression? But be careful not to bombard the interviewer with a long list - they may have a tight interview schedule to stick to. - Take notes, get noticed
Don't be afraid to take notes, not only does this look professional, but jotting down your interviewer's answers could come in useful as a reminder of important points if you're called to a second interview. Moreover, noting the job's benefits could help in your own decision making if you have one or more job offers. - Exit gracefully, then follow up
Leave the interview in a polite and assured fashion, meet the interviewer's eye, give them a firm handshake and smile. If you are interested in the job follow up with a letter. On your way home write a recap of the interview when it's fresh in your mind. Compose a follow-up letter and post it within 24 hours. This shows you're enthusiastic and organized and may set you apart from other applicants in the interviewer's mind.
