During my tenure in college, had a professor that would write 10s or 100s of line of code to do things that could literally be done in one or two. Pointed this out to him a couple of times, not that I had been a dev for 15 years at this point. Everytime he squashed anything I said. Comes to end of semester project. Within 24 hours of him handing it out, myself and team handed in final solution, which absolutely worked and fulfilled all requirements. We all got a not completed at final grade. Found out later that only 3 people in the class got an A, and they were the only females in the class, everyone else got a not completed. Immediately after having a convo with the "professor" and the threat of convo with dean of students, suddenly everyone got a passing grade. What a piece of human garbage.
