Rajkumar did not have enough marks to get admission in either engineering or medical courses so he did his graduation in commerce. Hirani helped his father in his business but he wanted to be actor in Hindi films. In college days he was involved with Hindi theatre. Suresh got his son's photographs shot and packed him off to an acting school in Mumbai. But Raju could not blend in and returned to Nagpur after three days. His father then asked Raju to apply to the Film and Television Institute of India in Pune, but the acting course had shut down by then and chances of admission to the directorial course looked slim as there were way too many applicants. So Raju opted for the editing course. He earned a scholarship, thereby reducing the load on his father's shoulders.
