ILP Location -- (TCS Training Center) --- (TCS ILP Center) TCS is operational at Mumbai, Pune, Bangalore, Bhubaneswar, Goa, Gurgaon, Jamshedpur, Kochi, Lucknow, Noida, Tiruvananthapuram location too. Above mentioned locations are offshore delivery centers (ODC).
Among all, Trivandrum has biggest capacity as it is meant for ILP purpose only. As far as training and other facilities are concerned like accommodation, food, trivandrum center provides awesome facilities. I am not saying that other centers are not good. It's just that trivandrum is best for ILP as you can roam around in weekends and learn and study during weekdays.
Overall, ILP provides great learning opportunities for freshers joining professional career. It grooms them and make them industry ready,
