MBA Dilemma: Is Rejoining TCS the Right Move?

Joined TCS as BPS trainee worked as process associate for two year applied LWP and pursuing MBA in finance from 3 teir college as in college, However, the companies visiting my college mostly offer roles in marketing and sales, which do not align with my desired finance-related career path.

Considering this, I am thinking of rejoining TCS to gain experience in a finance-related role. Is this a good idea? Additionally, if I rejoin TCS after completing my MBA, what salary can I expect them to offer me? I would appreciate some guidance on this.
