Engineer,

It very much depends on which area of Banking & Finane you want to work in. Its a wide area.

You can bring your engineering degree to work as Engineer but in the Banking & Finance field. You will be able to pick up a lot of Finance knowledge but of course you are still pretty much in the backroom.

Anyway, its still down to the bottonline where you have to decide which area you want to work in and not just blindly go into Banking & Finance. You might get back-fire without knowing your path clearly.
