It depends on what degree you pass out with!

With a Ph.D. you can get academic positions in good universities and institutions around the world.

With M.Stat / M.Math/ MS (QE) you can get into good doctoral programmes in India or abroad or join corporates/ research organisations as analytics specialist, economist etc.

After B.Stat/ B.Math one can join graduate programmes in Stat/ Math/ Economics abroad or MBA programme in IIMs. Very few people leave ISI after B.Stat/ B.Math though.
