I think that my GMAT/age combination didn't fit well into any of the US programs.European Schools such as INSEAD defintely require a 700+ GMAT score as it is a 1 yr program and the competition is intense.LBS might tolerate slightly lower score but you need to fit into the class(Age,WE,International Experience).You also have to very clear in your essays : why you want an MBA and what is your career plan.I think I wrote that I want to switch to finance which I think is very vague.You have to correlate your WE with the career path you want to pursue.It has to be relevant.
I targeted all the top schools in US/Europe.
Europe - You can try INSEAD but you definitely need 700+ in GMAT.LBS is looking for international experience but I think that the average age for LBS FT is 7 years.
Canada-I think Queen's is a good fit for people with Science and Technology/IT background.
Australia - AGSM is the top ranked school in Asia-Pacific.The average GMAT is slightly lower(660) but the placement salaries don't compare favourably against US/European Schools.
I think you need to ask yourself the following questions before you decide the school
1.Where will I like to work after the MBA ?
2.What kind of application package can I put forth with my combination of WE,GMAT,GPA etc ?
3.How well is the MBA school recognised globally ?
4.What is my area of interest ?Do I have a career plan in place ?
5.What kind of placement salaries do the school offers ?
In terms of competition,I think Canada and Australian schools are easier to get into.IMD,in Europe is a good school and likes older candidates(30+ age) but with only 90 seats getting in is tough.They concentrate more on work experience and have a pretty stringent admissions process.You will need to write 8 essays and if shotlisted for interview will need to fly to their campus(in Switzerland) to participate in a case study,presentation and interview process(Check their web-site).
European schools usually tolerate higher job experiences than US schools but with your experience(10yrs +),I think IMD is the only option.The average WE for both INSEAD and LBS is 7 years.
