Why are you leaving your current job?

Although this seems like a simple question, it can easily become tricky. Don't mention salary as a factor at this point. If you're currently employed, your response can focus on developing and expanding your career and yourself. If your current employer is downsizing, remain positive and brief. Under no circumstance should you discuss any drama or negativity; always remain positive.

"To be honest, I wasn't considering a change, but a former colleague recommended this job to me. I looked into your projects and the position and was intrigued by the role and by the company. What you're offering sounds like an exciting opportunity and an ideal match for my qualifications."
