IIM-Calcutta has unveiled an initiative, allowing its MBA students to pursue entrepreneurial ventures without permanently foregoing campus placements, said a statement from the institute on Saturday. The initiative was announced by IIM-Calcutta Director Alok Kumar Rai at a ceremony on Friday to induct 480 students into its 63rd MBA batch. He said that students who choose to spend a year building start-ups instead of participating in campus placements will be eligible to return to the institute's placement process the following year if they desire so.
