The chances of one getting front m-end investment bank roles just after finishing a PGM in IIM Kozhikode are extremely low.
This is because IIM Kozhikode has little to offer in the finance field as compared to A,B and C. The total financial roles available might be around 5% of the entire batch. There are some international opportunities in Indonesia, Africa etc.
IIM Kozhikode has amazing opportunities in mid-office level jobs. You can work here, get experience and then switch to the front-end.
The conclusion is that if you want to get a front end role right after PGP then go for A,B or C. But if you are open to learning different fields then IIM Kozhikode is the best option.
