Performing at job interviews is what does it. I conducted many interviews and noticed that people make two simple mistakes.

First, they impress the interviewers by obviously talking themselves up. Not impressive: employers are not interested in how great you are; they are interested in how well you could do the job.

Second, most people, given the opportunity, ask about pay. What you need to clarify is why you would wish to work for this employer. Being employed is like being married – it is a two way thing. It is also one of the most important relationships in your life.
