It's definently possible to make the move from Consulting to I-Banking. I'm currently pondering whether to jump ship and join a past client of mine, who want me to come on board and own the programme that I originally helped to shape. Typically if one wants to move into Front Office, as per Cap Grad's desires, I'm afraid it's a very, very long shot. Even if you have worked in I-Banking environments with Cap, since the types of work that traditional full service consulting firms offer is very different from those that are akin to a Front Office Sales position. My advice is that if you are serious about moving into sales, do an MBA at a Top 10 B-School.
