I am working in TCS..and I had done my 2 years in tcs and now my total experience is 7+ years and I am trying outside but still I haven't received calls ..can I resign and try outside ? Is that better way or not ? Please suggest me

You can't do this as, Every consultant and Hr aware about tcs notice period

But they don't know if you're in bench or allocated to project. Anyways I was suggesting the OP to have a reality check. If he is able to crack the interviews by faking his experience then he should go ahead resign else work on upskilling first.

But here no one is scheduling the interview when I was saying 3 months notice period

Thats the hypocrisy of companies
