I am aware of an engineer trainee in Wipro who was asked to leave after training because his mentor manager felt he is unfit to be an engineer. It was recorded in their system. 11 years down the line, the same engineer was head hunted by Wipro for a senior manager's position, because he had done some breakthrough work in his next job where he lasted for 11 years. He is a VP in Wipro today and everyone who works in Bangalore Wipro knows this.
Merit is an opinion and Wipro has some top class professionals to know that you are as good as your last job. So don't worry. World is big enough for you to do some breakthrough work and who knows, Wipro might just head hunt you back
