I’ll begin with my background. Post that, I’ll put forth my story of transformation from CA to an Investment Banker.
Just to mention, even a semi-qualified Chartered Accountants (IPCC cleared) can become an Investment banker
Note : Read this answer completely to get a realistic opinion. Half information is even more harmful than no information.
Few years back, I cleared CA final and started working with a Big 4 firm in audit team. Pretty much frustrated by the routine nature of work, I started looking for other options in Core Finance. Thus, terms such as Valuations, Equity research, Financial modeling and Investment banking were the first that came to my mind.
Finally, I got convinced by my fellow mates in the office (Who were in Valuations already) to make a switch to investment banking.
