i am german but have studied in the uk (undergrad and postgrad) business and management from a rather small and unknown university. i am currently working as a management consultant in germany for one of the top5. it really seems that in the uk the class and league issues is an issue. they wont even consider looking at your applicationa if you are not from a "target university". i think thats stupid....and they might miss out on some good graduates.
i suggest u getting some experience in an industry/line environment. i am currently looking for another job myself as i cant stand this bullshitting all the time anymore....
anyways, good luck to you
