Very few touch 50L CTC(domestic) in IIMABC. Check if it’s possible for you to move within the org itself, instead of dedicating 2 years.
Worst feeling would be if you get a lower package post MBA, and not the desired function which you want. This happens!
Most of the MBA placements are driven by students. Better to have very good repo with placecom team.
Best option would be actually to give GMAT and get into Ivy League schools. The ROI would be much better, although cost would be equally high. Check out European schools(where most of the courses are a year long).
P.S: cousin got admits from IIMB and C. He has opted for B. Have told him to have a good repo with placecom team. He’s NIT pass out with 2 years experience in DS(less than 10 LPA) package. For him, ROI would be better.
