Agree except I might be a tad harsher. I have two degrees from Iowa State: BA Architecture and BS Comp Sci. Though I loved architecture, the relevant studies were virtually useless in the real world. I started to realize this my junior year. Accordingly, I went forward for the Comp Sci degree hoping to gain footage in Architecture via the Computer Graphics path. But, sadly, I was enormously premature in that thinking. My career funneled me into the Comp Sci direction.I consider half of my college education practically worthless.
If I could only have taken 2 classes at ISU, MIS330 and MKT446, I would have gotten the maximum benefit because those 2 professors helped me so much. I taught myself sql, tableau, powerbi, and oracle from the guidance of said MIS professor. My MKT446 professor taught me how to properly read case studies and gave me advice of where to teach myself outside of class.
Oh, I majored in marketing and have a career in database development, risk modeling, and data visualization. None of what I took a class for besides MIS330 and that professor told me to learn all of these things to give myself a competitive advantage.
That as a precursor, I can honestly say close to NOTHING from my studies enabled me in the real world. Except of course, my own initiative. I self taught myself whatever it took to do the job. I never took the path of 'certification' for my knowledge because honestly it was a waste of time in comparison to progressing forward on the task(s) at hand. Sure, in hindsight, it'd make soliciting a new job easier because, quite frankly, the 'system' of filtering in a job search is so rigid and doesn't place enough emphasis on initiative, creativity, ingenuity, and cost effectiveness. When I interviewed candidates for a job under me, I never tested their knowledge. Why? Because it'll be antiquated in a few years. I placed the highest emphasis on initiative to learn, dedication to quality, and ethics. So, when commenting on blue collar jobs, I have the utmost respect for them as most are self taught and, of course, due to government oversight self certified.
