It reminds me of a really amazing set of coincidences that happened to me almost twenty years ago.
When I was studying at management school back in India, I did a summer internship in 1986 with a company that sent me on a market survey. During the course of the survey, I met an alumnus of the same institute who was working with an organisation called IFFCO (Indian Farmers Fertiliser Cooperative Ltd). His name was Ashok Tyagi. It's not a very common name in India, and I wasn't likely to forget it.
After I graduated and began to work as a developer with CMC Ltd, I was at the office of one of CMC's clients, NABARD (National Bank for Agriculture and Rural Development) in 1991 doing some requirements analysis. I finished interviewing one of the officers, then noticed that the desk next to him bore the nameplate "Ashok Tyagi". At once, I asked my contact if this person was a graduate of IIM Ahmedabad. It turned out he was. I was now certain it was the same person. After all, I knew no other Ashok Tyagis, and the only one I knew was an IIM graduate. Plus, IFFCO and NABARD both had to do with agriculture, so it was highly plausible that my old acquaintance had made a related career move.
But when the occupant of the other desk returned, it was a complete stranger. Nevertheless, I introduced myself to him as a fellow IIM alumnus, and we got to talking. I told him about the remarkable coincidence of his having a namesake who graduated from the same institute and worked in a very similar line. Ashok Tyagi II then smiled and told me, "I heard that there is a third Ashok Tyagi. He graduated from IIM Ahmedabad this year and joined FCI (Food Corporation of India)"
