What specific job training would prepare me to get a job at a large consulting firm such as Ernst and Young?

Your best bet is to acquire two main skills. First develop a core skill such as accounting, business or even a psychology degree with a focus on business psychology. Second, develop your communication skills. The ability to say and communicate the core skills you have is as big a factor as anything. Presenting your ideas in a way that both actually makes them understandable and stands out is huge in the business world. You could be the best accountant in the world, if you can’t get your ideas of how to fix a problem out there, who cares? Right!
