My bank did this once - called me out of the blue and started asking for answers to security questions. I asked them how I could be sure it was definitely them and they said to call the number on my card and ask for a particular department, which I did, and it turned out it was indeed genuine.
The fact that they had an immediate answer to the question obviously means that they were asked this question all the time. I wonder how many people happily handed over the info?
It seems that they now just play a recorded message asking to call, and then automatically hang up.
Makes me wonder, what if a bank just started all phone calls like that with: "Hi this is Bank, we need to get in contact with you, for security reasons could you please hang up and call the number on the back of your card?"
