Curious indeed. If you are so interested in helping out the third world, why are you so desperate to get into consulting? Surely working for an NGO would be more relevant? It may come as a surprise to you, but consultancies don't exist to improve the lot of society, they exist to make money from other businesses, which are mostly in the west. Whether you like it or not, the majority of consulting *is* about "managing budgets at blue chips" - and guess what, that's why they're interested in that kind of experience. And the small amount of pro bono/development work that consultancies do is largely a PR and staff morale exercise - they don't make any money out of it.If the bitter attitude you display here is any clue as to how you come across in real life, I'm not surprised you aren't having any luck.So, to answer your question: no, consultancies aren't interested in taking on failed teachers to staff their small amount of work in the third world.
