There are no prizes for guessing which city is the IT capital of India. But interestingly, the build-up in Chennai has all the ingredients to knock Bangalore off centre stage. Numbers suggests that Chennai will host the maximum number of software professionals in the country in three to five years. Chennai is already home to either the largest or the second largest development centre of the top six software services exporters in the country. No other Indian city can boast of this. In fact, it's not just the premier league of TCS, Wipro, Infy and Cognizant, which is adding jobs in the city's IT corridor, even emerging contenders like MindTree, Mastek, Polaris, Patni, Hexaware and Tech Mahindra are expanding their base at a hectic pace along the east coast.
