A few of my friends pursued the ICICI Business leadership program at NISM. According to their experience, the program is quite unique. 

• Selection to the program is done in three steps, i.e. written test, GD, and PI. Getting selected will not be difficult. However, the PI round can be tough. HR can ask tricky questions, you should be confident with your answers.
• The ROI of the program is excellent because you hardly invest anything. 
• The certification and the degree will help you if you want to switch careers. 

Security markets are a great area to work in and ICICI is an excellent organization that has produced many Stewarts over the years. If you are thinking of pursuing the ICICI Business leadership program at NISM, you should go for it.
