Re: So... is he an engineer?
When I graduated as a Computer Systems Engineer, there was a strong push to study for, and take, the Engineer In Training (EIT) test. This is the first step on the road to becoming a Registered Professional Engineer (PE), the certification that makes you a "Real Engineer" in the minds of state governments.
I looked at the test study guide. Lots of stuff about strain, materials, thermodynamics...well, you get the picture. Stuff I had only a passing acquaintance with in my undergraduate studies. Not a single question about impedance, modulation theory, filters, data structures, or anything else I had studied. The PE test is similar, but I think it includes some electrical power transmission sections.
Realizing that the subject matter was completely out of line with what I intended to do for a living, I took a pass, and have not regretted it. The number of PEs I have met in my career can be counted on one hand. I have tremendous respect for them, thanks to them, my house and the roads and bridges I travel on are safe (well, except for those in Florida), but a PE license isn't worth much in electronics development.
My professors all had PhDs, but I do not recall even one of them mentioning that he had his PE.
