Questions:
1. How are my chances for above schools? Especially Tier1 and Tier2 schools.
2. I guess 2 points in my profile may be flaws: Age (too old a little) and Employer (outstanding but not recognized to people in US and Europe). How much do you experts feel will them affect my admission? How should I make them up?
3. About my doctoral degree, will that be an advantage or a disadvantage (may be strange for B-schools?)
4. Any other schools you can recommend according to my profile?

Many thanks for your help!
