By Studying Only in IIT's are considered or Apt for companies like google,Microsoft etc ..?

Hello,

I would like to tell you that the syllabus covered in IIT's is far more updated as well as practically used rather than just theory like in colleges.

They use the concepts learned to implement new things rather than just mugging them up and passing tests.

And one more thing is that it does not matter from where you come for, these companies take in people for their skills rather than just college name.

Yes, IIT' s have a high chance as they have these comapnies coming for placements but you can always try from outside for these companies.

Hope this helps and all the very best to you!
