According to a retired diplomat who worked closely with Jaishankar on the Indo-US nuclear deal, it is this worldview of having served in world capitals key to the foreign policy of India that sets him apart in the IFS.
His experience, along with his approach towards the reshaping of the Indian foreign policy, first won him an admirer in former Prime Minister Manmohan Singh, and has now made Prime Minister Narendra Modi appoint him foreign secretary barely 72-hours before his career as a serving diplomat was to end.
What is, however, lesser known about the man is his wicked sense of humour and how fond he is of old friends. He is also known to be a strict man.
Jaishankar studied at the Jawaharlal Nehru University and counts Communist Part of India (Marxist) leader Sitaram Yechury and Nationalist Congress Party's DP Tripathi as close friends, although he was junior to the two of them.
Jaishankar comes from a well-known family.
His father, K Subrahmanyam, is the acknowledged father of strategic thinking in India.
One of his brothers, Sanjay Subrahmanyam, is a historian; another is former rural development secretary S Vijay Kumar.
His mother has a PhD in music from Delhi University.
Jaishankar joined the IFS in 1977, and started with a stint as third and second secretary (political) in Moscow in what was still the Soviet Union from 1979 to 1981.
He then served as an undersecretary on the Americas desk in South Block, which he headed as joint secretary from 2004 to 2007 --
