I have always appreciated the listings that divide the list between the “must haves,” even soft ones (e.g. 4yr degree, knowledge of X tool, Y years of experience, solid communication skills), and “our ideal candidate will have most of the following” (e.g. Y+3 years of experience, prior role in management, knowledge of Z regulation).
The 4 year degree one is still never a must have. The only things that are true must haves are certifications for federally regulated jobs, like requiring a PE.
