From 1973 to 1976, Jain worked for
IBM as a salesman for their data-processing operations in India. He was named "Rookie of the Year" in his region in 1973. He lost his job in 1976 when IBM discontinued their operations in India because they declined to allow Indian ownership of the company, as was then required by law. In 1986, he left McKinsey to work on insurance operations for Warren Buffett. Jain was invited by his former boss, Michael Goldberg, who had left McKinsey to join Berkshire Hathaway in 1982. In the annual letter to shareholders on 2014, it was suggested that both Jain and
Greg Abel could be appropriate successors for
Warren Buffett as CEO of
Berkshire Hathaway. In January 2018, Jain was named Berkshire Hathaway's vice chair of insurance operations and appointed to Berkshire's board of directors. == Philanthropy ==
