Applying to MBB firms

Hi, I am a CA student from India. I am about to complete my 3 years CA internship from one of the Big 4s but did not sadly qualify my CA exams yet. I am reappearing in November 2024 exams.

I have alongside my 3 year internship experience, a 3 year freelance experience in Strategy Consulting in a Spain based small firm where I had even handled clients on my own. The work involved creating pitch decks for raising funds and strategy advisory.

I want to enter the MBB consulting domain in India. What is the way ahead?

Given they hire only the top rankers from campus placements, my chances are meagre. But I have other internship experiences in research and business development roles.

My questions are:

1. How should I try cracking MBB consulting in India with my profile? Whether further studies are required?

2. Which position should I apply to?

3. Whether freelancing dedicatedly for 3 years gives me an edge?
