 I am a current student at one of the old IIMs.Yes the placements are awesome.U get fat money.But nobody talks about anything other than placements.There is no place for serious introvert people.95% students are full into alcohol and smoking and some into "maal"(Yes this is where our talented youngsters are heading).Your talent and hardwork is recognized less than how much can u drink and network with others.For all seedhe,introvert and hardworking people better get into civil services and do something for society and country rather than selling soap,cigerattes or financial products for so called MNCs
