MBA or MSc?

In general, I'm not a big fan of the MSc in Human Resources, because it can limit your options. While HR is a vital part of any organization and I think can be a terrific and rewarding career, it can also be the first positions that are cut and right now we're not seeing a lot of hiring in HR (at least in the states). If you think you might have interest in doing marketing, I'd recommend the MBA over the MSc. It will give you more flexibility, more options and higher pay -- this should be a decision made with a long-term view. Unless the MSc program(s) you're looking have terrific job placement, you're very confident about the career track you'd have in HR and are passionate about it, I'd look to expand my options with an MBA. You can always do a rotation in HR and stay there if you like, but when times get tough, you'll have the flexibilty to do other things.
