I remember my first week at Morningstar—sitting at my desk in the Mumbai office, opening up Excel, and realizing I had absolutely no idea what I was doing. Not the technical part. The smart-choice part. My manager dropped a dataset on my desk—about 2 lakh rows of fund performance data—and expected me to find patterns. I had my laptop, a mediocre internet co…

It was 6:47 AM on a Tuesday morning, and I was standing on the Central Line between Kalyan and Dadar, sandwiched between a guy eating a vada pav and a woman listening to a podcast at full volume. My manager had just forwarded me a rejection email from a candidate we'd interviewed the day before—a sharp kid from Pune, decent portfolio, but we weren't mov…
