Amazon SDE vs IIM C?

I'm wrapping up my final year rn, I have a PPO from Amazon as an SDE-1.

(~29L first year, 48 CTC)

I also have an admit from IIM Calcutta.m

This is my profile:

97/87/ 7.7 CG

BITS Pilani - EEE

The fees is not an issue, however i do want to optimise for my long term income.

My intention with an MBA would be getting into Finance or even Consulting but my UG Cgpa is a pain point so im a bit worried.

I am very lost and confused, and passing on either of the two feels weird.

I don't want to rely on cracking CAT later down the line.

Thoughts?
