Of the total 78 offers, 58 were pre-placement offers (PPO) and 20 were pre-placement interviews (PPI).
IIM-C has 454 students in the batch of 2013-15. The 78 figure at the beginning of the month of August was a healthy indication, the institute said.
Management consulting firms yet again led the way in terms of total number of offers made to the candidates.
The top four consulting firms - Mckinsey, BCG, Bain and A T Kearney gave 24 offers.
The General Management domain also saw PPOs from highly coveted firms such as Tata Administrative Services (TAS), the Aditya Birla Group, Philips, Pepsi, Bosch, Nestle, Shell, Vodafone, and iNautix, the statement said.
"Companies seem to be realising the importance of summer internship program and are hiring more through the PPO route. The current figures show an improvement in the economic situation as well as the profiles of the students at IIM-Calcutta," placement chairperson of IIM-C professor Rajiv Kumar said.
