The core of the city's IT trade — application build, maintenance and delivery for global clients.
Salt Lake Sector V and New Town Rajarhat together host around 300,000 IT professionals, and the wider Kolkata IT and ITES trade employs well over 260,000 people. Sector V is the older hub, dense with towers and floors and sitting at the eastern terminus of the metro's Green Line; New Town is the newer one, where the large single-occupier campuses are.
Kolkata competes on cost and on a steady supply of engineering graduates rather than on scale, which is why the city carries both very large delivery centres and a long tail of independent firms working in the same buildings.
