Man...its already too late for most of the positions. Most of the good companies hire people before January. Some send offers mainly in the months of October and November and few even give offers in September.

However, see if consulting is the job for you. I am not talking about IT consulting but rather, economic, financial and strategic consulting.
Search for those three keywords and you should have a fair idea about what these companies do. And, this is specially good if you think you might want to go to graduate school at some point in areas related to economics because these firms use econometrics extensively and expect the same from candidates.
