I was trying to change my current job and managed to get an offer from a boutique IB in Mumbai, but the hike is not great, 14 Fixed + 2 variable+ deal bonus, after I resigned, my current company wants to retain me and have given me an offer to join as a portfolio risk analyst in Bangalore, I am currently based here. I currently work as a VC analyst and wanted to try IB, so I was applying to IB roles. I have been an economics student, I am kind of interested to work in risk also. I am already 30 and have experimented quite a bit with my career, a bit unsure of what shall I do. The thought of moving to Mumbai from Bangalore is a bit overwhelming, considering Mumbai is just so expensive. Any Tips, suggestions on how do I make a decision?
