The man that drives a train is called the Engineer, and he may not have an college degree at all.
A structural engineer dang well better have a board certified degree to do his job and certify the design of a structure will hold up to the intended purpose.
The acid test for must engineers is personality. If they mostly look at their own shoes when in conversation, they may well be an engineer. If they look at other people's shoes they are an extroverted engineer. If they look you in the eyes, and claim to be an engineer be suspicious.
