If you are looking for THE top MBA programme in EUROPE, I would say that INSEAD and LBS are the schools with the best programme, brand value, recruitment and network. Some may say that INSEAD is best, while others including me argue that LBS is best in Europe.
Both schools are very well-known all over the world. INSEAD with its 10-month programme is quite short and highly regarded for consulting. LBS with its 15-21 month-programme is famous for finance and global management. However many LBS candidates are recruited from consulting organizations. IMD Lausanne's 10-month programme is also highly regarded as a top school for consulting and management.
Furthermore, I think that IESE, Ox-bridge, IE, HEC are also excellent programmes, depending where you want to work after your MBA. However, those schools are -in my opinion- not as prestigious as INSEAD, LBS & IMD.
+1 I think this is spot on. Totally agree with catgmat. More than the number of graduates it places in consulting firms, about 30 or more MCs come from the Big4 to study. It would be a great opportunity to learn and network with them.
