How do you start a career in finance without a finance degree?

Three years back I was also in the same situation get the finance job through campus placement even though I don't have a finance degree, initially for some time it will fill odd but after a year you will realise if u r hard working and having good analytical skills then whether it's a finance,sales or marketing u will do excellence...in the long run if u plan to switch for some company finance degree matter for some it not if ur cv spoke well.
