In my opinion, for students with work experience doing an MBA is easier compared to students without work experience. Although there is no relation between the ease of subjects and your work experience, it sure proves to be slightly beneficial. This is because they are able to relate to the study and learning better.
Having 2 years of work experience will certainly add to your chances of getting admitted in ISB Hyderabad and your approach, basic understanding, GRE GMAT score, leadership skills are the other factors that contribute to the same.
A friend of mine who recently graduated from ISB Hyderabad told me that there was an international tennis player, a retired army colonel among his classmates.
