If you can identify on your weaknesses and sell them as a strength, you win every time because most people don't. Most people focus on strengths instead, thinking that knowing your weaknesses is...a weakness.

I always say, my weaknesses are my strengths. I am able to identify my weaknesses and work on them to build them into strengths. In essence, the ability to identify weaknesses is a strength.

After I explain this I always ask, "Out of sheer curiosity, what are YOUR weaknesses?" or "What would you say the companies weaknesses are? This shows that you understand everyone has weaknesses and it's not the end of the world, it's being aware of weaknesses that matters, It also usually becomes a 10 minute segue where you can lower the staunch, professional focus of the meeting and make it a bit more of a conversational interview, which is where you can make the most ground and take control of the interview.
