IIM Calcutta will let you retain your individuality and treat you like an adult. You will not be treated to a deluge of tests and quizzes and readings. If you are someone who is comfortable in finding his own meaning of what an MBA is, come here. Rigor here is defined by the sheer analytic depth and not by the number of hours you pore over your books. You will enjoy and find your own pace but the quantitative concepts even in Human Resource Management will leave you struggling with your analytics.
