I came across this fantastic website which I thought I would share with my candidates.  Not only does the website provide excellent pointers on what to do when attending an interview, but it also depicts some hilarious real-life videos on how NOT to interview!

I hope that the opening paragraph below tickles your curiosity:
“What is it that certain people say or do while interviewing that makes them stand out? Why do some people struggle to find work, while others land a job in no time? I wanted to know, and the only way to find out was to experience the interview from the other side of the table. If I could be the one asking the interview questions, not answering, I could see first hand what made candidates stand out. I could then take that knowledge and cater my behavior in any future job interview to give myself the best chance of getting hired.”
