Names can be as malleable as clay, especially if their original solid form is more than 2-syllables.
While western English names have a ready-made shortened form - Robert becomes Bob, William becomes Bill etc. - Indian names, outside of families, are usually spoken in full. Still, Generation X onwards, many young Indians have also adopted this practice, such as Siddhartha becomes Sid. In India my name did not survive in the two locations where I stayed. Among my friends I was known as Eddy in Chandigarh, and Andy in Bangalore, and many tangential variations.
I kept my name intact in New Zealand, hoping for a new start, till my recruitment consultant advised to pick a shorter version - so Aditya became Adi became Eddie.
Predominance of English usually decides the direction of the name conversion. What happens it was in the opposite direction, see in the great video below brought to my notice by Prasanna, or as we call him - Praz.
