I think , no one is going to see where are you hail from and what did you do . companies are interested in what you may do for them . an MBA degree may be an evidence that you are serious about finance . Like you , I am of science background , and also want to enter into world of finance . I think , students of science background are able to work in financial institute because we can handle data and information better . science background may be a strength point , not a weak point .Posted from my mobile device
Well, that depends, it can work both ways. If someone's been a software developer for 20 years, then I don't think it can work in his favor, however I have seen people with PhD in science getting into finance. Then again, in most cases I don't appreciate a PhD holder more than I do a MSc holder (plenty of my friends have a PhD and I've seen really dumb people getting one, so, sorry for the bitter truth).
I suppose there are positions in finance that a sciences degree can be used in your favor which obviously I'm not aware of..
