Congratulations that you have been from IIT, and I hope you are up to it and deserving.
Its a common misconception in India that they get it because they are brilliant...well actually in any admission in Inida where 3.5 lakhs appear for exam you are.. ...you get it because...because others miss it.....there are many geniuses and bettter students.. who falter at the alter.........in case you dont agree...then you are overestimating your virtues......
For a change, lets consider what if you had missed it ...... and had to look for other avenues....... would still stick to your opinion....
I dont need an answer....its for introspection.....in case you can ....... as it can be never possible without deflating your ego
