If I Decide To Stay In My Current Company

Hi,
I am working in a MNC (IT farm). I have recently got an offer from TCS to join as an experienced professional. So I have resigned from my current company and currently I am serving notice period. But to retain me, my company is now giving me an offer which is more lucrative than TCS offer. So I have decided to reject TCS offer and stay back in my current company. My joining date in TCS is on 27th June.
My question is - in future, if I apply for a job in TCS again, will my application be considered as potential/valid?

Depending upon their policy and data base, they may reject your application. They may consider you unreliable.

One should not be so fickle minded.
Accepting offer letter and then reneging on it because your old employer has lured you with better offer might resulting TCS marking you out as illegible for future offers.Only a man who knows TCS internal rules can answer this query correctly.

Your question is quite irrelevant, as neither we are the spokespersons of TCS, nor future is known to any body. Future is always uncertain.
