Tier 1 IIT NIT Tag privilege

When we hear a person is from X IIT or NIT,we think they are smart. Irrespective of how he performed after he came into IT field or any field, he will still be treated on the top. His tag is for his life time. Jo diktha hain vo biktha hain as what people say, If you see he's from IIT or NIT, you will hire him. I was thinking this is not the case if you work hard you can beat them, intelligence is what matters etc etc all this is bull shit. Get a good IIT/NIT tag and you will be life time settled. Every jump you make people will see ur degree college subconsciously value you if you are from tier 1. Considering all this , since this is case with colleges, i feel if you are from google, Microsoft or such big tech other companies will blindly have faith in you. I mean again sane logic. My question - To have stable IT job, should i try to first get into big tech, and then even if i get laid off i feel i will be valued for my ex Company and then i can grab new offer. Should i do it ?!!! Btw im 25M fed up with this competition and i need some stability in life. Forgive me for English, its 12:28AM and these thoughts are disturbing me.
