As an academic moving into consultancy, I think I am well placed to answer this. All of the top consultancies want top graduates, which without question means candidates from the best institutions. Now, any ranking system is completely arbitrary (and generally idiotic), so I think it's better to look at which schools carry sway with employers no matter where you are in the world, and not who is 'better' than whom. In the UK:Cambridge, University of London and Oxford (the golden triangle)Within University of London itself, University College (UCL), King's College (KCL), London School of Economics (LSE), and Imperial College Other high flying UK universities include UMIST (University of Manchester Institute for Science & Technology), Bristol, Warwick, Durham, Sheffield, Liverpool, Edinburgh, St Andrews, Birmingham, Aston Business School, London Business School, Leeds, Bath, York and Cardiff.Some but not all of the most prestigious UK universities, with the greatest research income belong to a collective known as the Russell Group (much like the American Ivy League, but with 19 members instead of 8).See: russellgroup.ac.ukIn the USA:MIT and Caltech are the kings for tech research. Also, other top notch places are UPenn, Yale, Princeton, Stanford, Harvard, Columbia, Brown, Dartmouth, Cornell, Chicago, Johns Hopkins, Northwestern, Duke and University of California (including a number of colleges such as San Diego). Many of these places are multi faculty and not tech research intensive, so do think about that. There are of course MBA specific schools you might consider if a Business education is really the main thing you're after. The top tier for this would include:In the USA Harvard and UPenn amongst others(but I couldn't say which is "better"). In France, consider INSEAD.I'm better placed to tell you that in the UK, the following are highly regarded: London Business SchoolUMISTAstonSaid Business School, OxfordCambridge Business SchoolAnd in that order. DICLAIMERThis is a personal response, so please do read it as such and thoroughly investigate your choices in depth. Hope this is a good starting point for the education available in the UK and USA.
