Can a 16 Year old work at a Bank?

Not if your math is as horrendous as your English.

Yes

It depends on their hiring practices.

Maybe as a janitor, not someone who handles any money.

You may be able to get a paid or unpaid internship. The laws are the same for a bank and a grocery store. I had to go to a one day seminar and sign permission (and responsibility in the event of theft or selling liquor to minors) for my 16 year old daughter to work at a grocery store, but they hired her. When I was 16 I worked construction, in a garage, and on a political campaign. look on the internet.
