you should consider both. A number of your competitors who are pursuing similar jobs will bring both to the table. My classmates who are armed with both have done very well.
Is there one you should consider before the other if you're absolutely determined to get both?
I would say take the CFA first, it's easier than the MBA to start. Just register and study away, and it fits around your schedule. As for the MBA, it seems like its a bigger commitment and will require you to work your schedule around it, not to mention it takes about a year to apply/get in.
