Is it even legal to do checks on "can he manage his own finances"? Even in India (where you can have checks of criminality and so on at the point of hiring, especially in large companies, thanks to the focus on Outsourcing) people don't disclose their financial information to employers. Banks and financial institutions will turn any inquiries down unless you are a law enforcement officer with the proper paperwork.
