Prospective Monkey

Hello! I am an Undergrad Engineering major at a Non-target. I have developed an interest for the fields of Management Consulting and Investment Banking (M&A) for several reasons. I have a few questions regarding my journey to get there:

I have discovered that Goldman Sachs Operations recruits at my school. I was wondering if I should take that job get into a top MBA program so I can fulfill my dreams of breaking into MBB Consulting or Mergers and Acquisitions? Or should I take the plunge and network extensively to land a entry-level job there.
