Stung by the economic slowdown, campus hirings in a number of B-schools, apart from top institutes like IIMs, have dropped by 40-50% and pay-packages by 35-40% this year, according to an Assocham study. The number of admissions have declined as well with 190 B-schools closing down in 2012 and 300-500 institutions having become defunct because of not filling-up enough seats.
