Kolkata's technology sector centres on Salt Lake Sector V and the newer New Town and Rajarhat developments, which together form eastern India's primary IT hub. The work here skews towards IT services, analytics and back-office delivery for domestic and international clients rather than product engineering, so demand concentrates on data handling, reporting and quality-assurance skills. Living costs are lower than in Bengaluru or Mumbai, which means candidates here often weigh a local role against relocating — and employers compete accordingly.
