Xiaoyi,Mif or MBA or both, the choice all depends on your career aspiration, which should be based on your experience and personality. As for GE experience, again, it is hard to give a general answer.
There are mifs who already has a top MBA even PhD but they want to change careers either geographically or functionally. Some are sponsored by companies as well.
Major differences between the two programmes: 1.Lots of soft-skills and general mgmt trainings in MBA while Mif course is more quant 2. MBA recruiters are much more diverse in terms of industries and functions. MiFs can be competitive in market and derivative jobs while 1st year MBAs in general are ill-prepared for such positions. 3. Since Mif programme is shorter, candidates are expected to have very clear and focused career plans.
