Firstly it's not up to you to choose Hyderabad or Mohali. You can just apply to ISB and the campus is allotted on the basis of a strange algorithm.

Now coming back to the question of your chances of getting into ISB, it seems I know nothing about your profile. I will state some general points regarding ISB Hyderabad admissions 

• The first and foremost requirement is entrance exams like GMAT and GRE. The average is around 710 for GMAT and 325 for GRE.
• You need a minimum of 2 years of work experience 
• You require and Letter of Recommendation and introspective essays
• You need to feel a comprehensive application form that attracts the judges

More than work experience, the quality of your work and achievements matter more. While writing the essays mention the unique qualities and roles you have fulfilled in life.
