Dear Aspirant,

To get placements like IITians and other top engineering students, you need not to prepare for some exam, but prepare for skills required in the top MNCs like Google.

You have to prepare for the competitive programming on platforms like leetcode, and prepare for competitions like Google Summer of Code, etc.

Moreover, you have to learn fundamentals of DS, ALGORITHMS and System designs,

You also have to make projects in some technologies that are relevant for the role you are applying for,

Hope this helps. Thank you.
