B.Tech in computer science and engineering can help getting hire in google company

There are 2 parts to your question - first is that just completing CS from any x, y, z college doesn't guarantee you a job at Google, second is that after you graduate from a reputed college, either Google comes to your institute for campus hiring or you apply at Google after the completion of your course individually. However, remember, you need to score well in your CS degree and also you need to have sound knowledge of your subject.

Kaun se college me hai..

Definitely, Google toh Cse walo ko hi recruit krte hein
