I came across my EIT certificate just a few days ago. At my university, they just sort of assumed that all graduates would eventually end up in a career where a PE license would be required, so they encouraged everybody to take the EIT exam. Not at all required, encouraged, or rewarded in any way in the industry I was in, though I did have a few colleagues who were PE's.A degree in engineering and a difficult test is required to get a state issued engineering license. As a licensed engineer my stamp is on lots of engineering documents and plan sets. Without a license you are limited to technician level job.
Also have an MBA. Used finance education and knowledge to develop cash flows, predict project cost of capital and to acquire bond financing on mega-projects.
Cheers.
