If you are hired, what kind of training do you feel you will require before you start making a productive contribution to the organization ?

Now this is a question which entirely depends upon the kind of work you are planning to take up. If job profile matches with your educational qualifications, you can reply about the same & show an inclination to start your job right away. But if you are switching to a relatively new field, you need to show some interest in preliminary training to allow you to get a grip of things.
