HN - first post here.
I've read a lot of posts here about a Do It Yourself MBA or (more recently) teaching yourself Financial Engineering. While the real prize is the knowledge itself, how do you credibly demonstrate this self-taught knowledge/skill to potential employers? I don't imagine that I can just put it on my resume and have an employer believe me.
For some professions, like programming, simply working on a project or two would suffice. There exists ample opportunity for signaling. Perhaps there's some analogue for an MBA or MFE?
If you know for certain you want to be in business or finance, why not simply attend a top school. It only takes two years, which is nothing in the grand scheme of things. You'll make great friends, expand your network tremendously, and learn a lot, particularly if you go in with a very clear idea of what you want.
Of course, there is a downside -- tuition and opportunity cost. But it doesn't sound like your opportunity cost is that high and tuition, while expensive, is often worth it. I know plenty of people who were earning $40k pre-MBA and $160K after. They are also doing much more interesting work. It's absolutely essential, however, that you know exactly what type of job you want and what is required to get it. If you want to go to McKinsey, you essentially need to attend a top five school. Schools are definitely not worth it if you fritter away your time or decide you don't like the career path you've chosen.
