Mahendru was born to a Russian mother and an Indian father in Afghanistan. She had a "gypsy" childhood, regularly travelling between Saint Petersburg and Frankfurt before moving to East Meadow in the town of Hempstead, New York, at the age of 13. She is fluent in German, Russian and English, and also speaks French, Persian and Hindi and initially wanted to use her "ethnic ambiguity" to work for the United Nations. She was enrolled at New York University for a Master's degree in international relations, but dropped out to pursue acting. She then moved to Los Angeles and studied improv at The Groundlings.
