In stock exchange filing, Bengaluru-based IT firm Mindtree Ltd announced the appointment of Debashis Chatterjee as the new managing director and CEO (chief operating officer) of the firm, after engineering giant L&T Ltd took over as its promoter on 16 July.

Chatterjee served as the president of global delivery at Cognizant. His term came to an end on 31 July at the American IT services company where he also served as its global leader for digital systems and technology practice.

He was appointed as the CEO at Mindtree for a five year term-from 1 August 2019 to 1 August 2024. Chatterjee is now the third CEO of the IT firm which was founded 20 years ago.

SN Subrahmanyan, who currently serves as L&T group's managing director and CEO, was appointed as Mindtree's new non-executive vice chairman.

Rostow Ravanan, who was part of Mindtree's founding team, resigned as the company's CEO on 5 July, after the completion of L&T's open offer to acquire Mindtree, which was being called India's first hostile takeover in the IT space.

With Chatterjee's appointment, Mindtree for the first time in its two-decade of existence will have a non-founding member as its CEO.

Chatterjee is a mechanical engineering graduate from Jadavpur University, Kolkata.
