This is perhaps the most open-ended question of them all and is typically used by interviewers as a warm-up question to give you the opportunity to shine. But resist the temptation to start talking about your life history. What your interviewer is looking for is a quick two or three minute snapshot of who you are and why you are the best candidate for the job. So keep your response relevant to the position you are applying for.

For example:

I started my media sales career five years ago as a telesales representative, rising through the ranks before gaining promotion to sales manager three years later. I am now responsible for training and developing a team of 15 sales consultants that are currently the company's best performing sales team.
