Does being from an IIT/NIT play any role in one's growth in a company like TCS/Infosys?

It plays role in getting you a job but after that everyone out there are of the same potential and your progress depends on your performance. (Except an IITian might have an added advantage when is BOSS is also from IIT)

I would kindly disagree with the answer that a person from IIT/NIT should not be joining Infosys/TCS. Infosys does product development and management consulting and data science in many verticals in addition to regular IT service work (support / development / maintenance). The answer depends on -- 1. The position you are looking for when joining the company 2. What experience/expertise you already have garnered during your stint in the IIT (or after that) If you join TCS/Infy as one among the hordes of 'Software Engineers' hired in mass placements, then your IIT pedigree does not give you any advantage by default during or after training. However, I would imagine using the brand to network and try to get doors opened to opportunities inside the company. Having said this, if I were a manager in either of these companies, and a person came to me with IIT credentials, I would still look at the value/experience/skills the IITian is bringing to the table before taking any decision. Infosys specific answer - If you manage to get very high grades in Infosys training, and/or have great ideas and/or would like to do research work, then perhaps you could try to get into Infosys Labs - which is the R&D wing inside the company - and perhaps work on some exciting stuff. If you have an MBA from IIT, and relevant prior work experience, then perhaps you could try and see if it is possible to get into a 'Consultant' or 'Senior Consultant' or higher roles. Post MBA freshers with no prior work experience usually get placed as 'Associate Consultant' which is a job level below 'Consultant'. Sorry - gotta start at the bottom, get experience and work your way up mate. The obvious advantage of joining as a 'Associate Consultant' after an MBA is that a person joins at job level higher than the 'Software Engineer' role, and gets a much better salary package.
