MBA from Tier-1 college after 4 Years of experience

I got a call from SPJIMR for interview but I am not even sure about doing MBA. I will have 4 years of experience by July next year and CTC of around 27LPA. 

I am not sure MBA is the right path for me or not even if it is from a Tier-1 college. Can someone help me with this? Does the investment of MBA makes sense or should I continue in my current role as a developer? Until now I have been interested in coding and tech stuff but down the line I am not so sure.

People have told me it depends on what you want to do further in life but i am completely unsure about it. I thought I'll give my exams and worry about wanting to do MBA later but even now I am not sure.

if anyone has any similar experience or can advise me then please do comment
