Know your own resume - if asked a question about something you have written, don't fumble - remember YOU WROTE IT. Be ready to respond to any and everything you have written on your resume.

Research not only the company you are interviewing with, but industry trends and who the competition is. Trade magazines, annual reports and the Internet are excellent tools.

Be as prepared as possible for the type of questions being asked - read up on behavioural interviews.

Know what questions you want to ask them ahead of time.

Don't exaggerate, but do talk about any related accomplishments you have had, citing concrete examples involving your role, the time frame and what the successful end result of your input was

When you must discuss money, know your own worth in the current market but keep an open mind as to what else the company is offering.

And finally - remember to look and act professional at all times during the interview process.
