Good evening everyone, I have questions regarding PhDs in the ENGINEERING field. For reference I have my BS in Aeronautical Engineering. 1) Is earning a PhD with the intent of going into industry research and not teaching wise? 2) Do the majority PhDs who enter the workforce acquire jobs which require an advanced degree and do research similar to their thesis? 3) I have heard from an acquaintance in engineering that 5 years experience in industry is more valuable (from a professional standpoint) than 5 years spent on a doctorate degree. Is this true? Remember that these questions only pertain to the engineering sector.
