Hello.
I already have an offer for IE MIM+MIF, but I want to apply at LSE as well. I am 23yo russian with a 710 GMAT, a 3.8/4 GPA (2014) and a two years part-time and one year full-time experience at quite big local manufacturing enterprise.
The question is about the difference between MSc International Management, MSc Management and Strategy, and MSc Economics and Management. Please, provide the details.
My goal is to switch to the consulting.

The Management and Strategy program would probably best suit somebody who is looking for a career in consulting. Do some research first - do they consulting firms you are targeting actively recruit MSc's? If so, from which schools? My sense is that LBS would probably be preferable over LSE, although I am not sure that consulting firms recruit MSc's as often as they do MBAs.

The IE program is highly regarded and has good stats for international mobility, meaning that if you were aiming to transition out of Russia to another country it would probably be a good choice. However, there's always the issue of language - if you want to work in Spain after graduation you'd probably need Spanish skills.
