sakky, many of the people I knew that went into non-engineering fields upon graduated had planned on doing it from when they entered college. They wanted the skill sets that engineers learn, because it's so highly valued, but they would never dream of actually doing engineering for the rest of their life.
Most of the engineers I know that changed their major due to "not knowing what engineering was" still usually stuck with engineering, but just changed their field. About half of my Materials Science friends had come into college planning on being ChemEs. The handful I know that switched out by choice went to math, physics, chemistry, or biology; typically fields tech schools are still pretty darned respectable in. The only people that completely left engineering were those that were the bottom of the class. They all switched to business.
