If you were in India, the last name Jain is enough of a brand if you need someone who can grow the business. The community/ last name is synonymous with successful businesspeople.
That isn't really the case. Jains are of all kinds. From monks to businessmen. He was probably hired because of his IIT + Harvard degree, not his surname.
I’m sure you’re right, but every Jain I’ve ever met has been impeccably ethical which is an attractive trait in a person you’re asking to manage billions.
