Improving your CV is important when you join a B-school because candidates are not shortlisted based on their CVs.
A basic approach to upgrading your CV would be to add points to portray a balanced profile (academic, work experience, extracurricular activities, competitions, certifications, etc.) or to be remarkable in a specific field.
Extracurricular activities, academic honors, prizes, scholarships, and career objectives were all requested on the application forms for FMS Delhi. During your PI round, you should expect a handful of questions from these areas, though the topic could be anything, including current events and your graduating course. So you must be up to date on current events and be prepared to speak for a few minutes on yourself or any random topic.
