Bhagat then went on to do an MBA in Marketing from the Indian Institute of Management, Ahmedabad (IIMA) and graduated in 1997 with an MBA degree. He was awarded as the "Best Outgoing Student" of his batch. In June 2018, IIMA awarded him the "Young Alumni Achiever’s Awards 2018" in the Art & Entertainment category.
After graduating with an MBA in 1997, Bhagat was placed through his campus at Peregrine Investments Holdings in Hong Kong. However, Bhagat lost this job within six months as the company closed its operations in 1998. His next banking job was as an investment banker with Goldman Sachs at their Hong Kong office. Despite being unhappy with his boss at the bank, he stayed on due to a lack of options. Bhagat kept this boss in his mind when he characterised the villain in his second novel One Night @ the Call Center. Bhagat spent most of his time at the Goldman Sachs office in writing, completing and revising drafts of his first novel, Five Point Someone. He worked on 15 drafts of the manuscript. He kept contacting publishers and was rejected. After two years, Rupa Publications accepted his manuscript and offered to publish it after some feedback. After the required changes were made, the novel Five Point Someone was finally published in 2004, when it was declared to be a best-seller.
