Do you have any blind spot?
 

It is a trick question. So don't specify your actual weaknesses. Instead of this try to show you are very team oriented

For example:

"I would say everyone has blind spots and I would too. And that is why I believe in teamwork because when you are a team you can point out other people?s blind spots and they will do the same for you."

Note: "don't admit failing as a blind spot. A failure is not a blind spot."
