The actual average in-hand salary at ISB is around 1.25–1.5 lacs per month.
That is roughly a CTC of 20 -24 LPA.
I was actually considering ISB since I have a strategy consulting background, but the in-hand salary is something I save every month. So I had to postpone the idea of going for ISB.
I think its one of the best B schools in India, especially for people with 2–5 years of work experience.
