Lets Discuss about KT

If you are in TCS, yes... Do not engage in KT and continue having dependency . The company is not playing straight neither should you.

Yes Providing KT is a very very big mistake in TCS, at least you need to maintain 40 to 50 percent dependency else you regret, because I am one of the victim, next month they are releasing me

Never teach more than 60% of what you know. Keep dependency on you which will create long term leverage
