The MBA course from ISB or the Indian School of Business specializes in offering Operations and General Management roles. My cousin is from the same B School. She has listed down some reputed companies that offer you Operations and General Management roles.
Apart from these specialty roles are also offered by big firms like Apple and Fung group. Many start-ups offer good packages in Operation and General Management roles. But IIM Calcutta is nowhere behind in this aspect. Both offer equally good roles.
