Hi Harshit,

Since you have graduated in the field of chemical engineering, and also have some relevant work experience under your belt, it will be best for you if you go for MBA in Operations or Supply Chain. If you do Marketing or Finance it will be a completely new field for you and therefore reduce your effectiveness as well as make your work experience irrelevant. 

operations management will benefit you by boosting your current salary as well.

Hope this helps,

Good luck!
