The absolutely best thing you can do when you have a job interview scheduled is to be there on time. In this job market, you're lucky that you even got called.
One of the worst things a job applicant can do is what happened to a friend of mine who is hiring last week. The candidate didn't show, not only wasting a block of interview time, but also getting herself on the making a really bad impression list.
She emailed 25 hours after the interview to ask to reschedule. He declined and I don't blame him. Who would want to hire someone who was a no show?
Of course, there are legitimate reasons why you may need to reschedule. What's important is to let the company know in a timely manner that you won't be able to make the interview and to try to secure a new interview date when you talk to them. Here's how to reschedule a job interview - the right way.
