I am going to be a bit more negative here as I think you are potentially setting yourself up to fail.Your chances of getting into MBB, or in fact another 'top-tier' consulting firm are not great - this is simply a numerical fact based on applicants to places, irrespective of your background.You graduated in 2012, and so by September 2014 will have over 2 years to fill on your CV.As a recruiter I would be looking to see evidence of really strong work experience and career progression within a big name company. But even with that you would be struggling as you would be difficult to place, falling between the experienced hire/MBA candidates and the undergrads.Your solution to this seems to be to 'maintain' your undergrad status for longer by further internships. Despite the big name brands you mention, if I was a recruiter I wouldn't find this impressive, I would ask you why you haven't managed in this time to complete two years on a grad scheme.I think you are playing with your future here due to your 'consulting or nothing' attitude. If it turns out to be nothing, what is your plan B? and plan C?If I was you I would apply to every good undergrad job I can find, accept the first one that comes along, do it well and, if still obsessed with consulting in a few years time, then reapply from a position of strength, or go to business school and come in at a higher level.That's just my 2 cents though. My third cent is that I would personally much rather work at Rolls Royce than in consulting anyway...
