I'm weighing in as an observer. Just as it was hard to get into a life science course during the Philip Yeo days, it's as difficult if not much more difficult to get into a good position in th financial services. I see that you are at a stage where you can't spend another 3-5 years "betting on a career strategy", so my advice is for you to be careful and if possible try to stick with something that you're familiar with. It's just too easy to have lofty ideas about something you're unfamiliar with.
