Linked slightly with the last point is your health.  Bad health is a major reason for ensuring you are not called back for a second interview or offered the job.  If an interviewer has any doubts about your health, that will be the end of it I’m afraid.  Unreliability for any reason is bad, but for health reasons makes you a complete “no-no”. Want to know how to look good? Stay healthy!

Look at it from the hirers’ point of view.  Would you hire someone who was constantly off sick?  No, you wouldn’t.  So if your sickness record is bad, address it now.  As a manager, I have had to deal with employees with a bad sickness record.  I can assure you there is nothing worse from the employers point of view, believe me!

Of course, the flip side of this is that you should radiate health and vitality when you attend an interview.  Therefore, if you do feel under the weather on the day you are due to attend an interview, you are better off cancelling.  If you are not feeling your best, you will not look your best, and you will certainly not perform to the best of your ability.
