Honestly speaking, a career in investment banking should not be considered by the new IIMs. It’s a too ambitious profile to match the relatively new curriculum of these IIMs. Even if you are in a top B School, you will have to remain among the top students to get placed for a front-end role. One can still get roles in corporate & business finance but getting roles in Investment Banking is rather difficult.
Yet if you are not choosing an older IIM and want to choose a newer one, IIM Trichy is the best among them. The order is
IIM Trichy > IIM Udaipur > IIM Ranchi
There are many B Schools apart from IIMs that offer great Investment Banking roles. These include SPJIMR, JBIMS Mumbai, IIFT, and XLRI.
