Dear Axechik,
Thanks for your post!
In terms of your question, I must admit that you haven't really provided me with much information to go on. While your GPA and GMAT suggest that you should be looking at top-tier schools, there are many questions I'd need answers to before making school-specific recommendations. For example:
1) What are you hoping to do with your career post-MBA? Are you looking to change industry or function? Stay with your current firm and move up incrementally?
2) Where do you hope to build your career? In the United States? United Kingdom? India? China? Location/region can be important when determing a target school.
3) What sort of network have you built thus far via your education and career? Is this network located in the market/region you are targeting post-MBA?
4) Do you have a preferred teaching method? There are many teaching methods out there, ranging from lecture, case studies, class discussion, team projects, experiential learning, etc. Some programs use all of these and some are more focused around a particular method. Knowing your preference in this regard can be helpful as you target schools.
5) Do you have a preferred program size? There are schools out there with 150-300 students per year (typicaly very close-knit/supportive environments) and programs that graduate 700-900 students each year (typically have more resources, larger networks).
6) Why are you focused on one-year options? Is this driven by financial concerns? A desire to get back to your current job ASAP? There are a number of one-year offerings out there, but I just want to be sure I understand the logic behind this focus (since it's a very different path to be heading down vs. the two-year model). If you are interested in looking at one-year options, you might start with INSEAD, Columbia (J-term), Kellogg 1-YR (assuming your ugrad was in business), LBS (you can accelerate the pace at which you go through their program), Oxford, Cambridge, etc.
7) What demographic and other background information can you provide? Are you male or female? 27 years old? Where are you from? Have you worked/lived internationally? Are you active outside of work?
Finally, getting back to your stats, a 3.6 GPA should be competitive at a top-10 program, whereas a 680 on the GMAT is a bit below average. Have you taken the GMAT more than once? If you are looking at top schools (e.g. global top 20), you may want to consider raising your GMAT to be more in line with the 700+ averages that schools are posting these days.
Feel free to post further details if you'd like more feedback.
Best of luck,
Graham
