I'm an EE with RF design and antenna chops, but I've been hired into a few jobs where I had only the vaguest idea of what the work actually is. One was a configuration management role, and the other was a software test engineer (and I've coded maybe 150 lines in my lifetime).
Neither of them had any mention of these activities in the postings, and both of them were specifically for EE's with requirements to understand antenna and radio systems. The interview started to shed light that it wasn't exactly what I had in mind, but certainly there would be the opportunity, so I was told.
To me, a disclaimer that mentions you may not be doing anything actually related to this posting would be nice.
Generally speaking:
1) what is the actual, physical, tangible, product?
2.) What is my actual, specific, day-to-day role for this product? Or how will I fit into the creation of this product?
