I tend to spend a large amount of my free time reading up on courses in my under-graduate study such as Theory of computation and Natural language processing.
Although I do it for my personal pleasure, I was wondering if there was any way I can use that to enhance my resume. The reason I am asking this question is because the subjects I study are fairly theoretical which I think doesn't factor much into hiring decisions made by companies. I have already read "Is it ok to put the courses that I have self-studied in my resume? what should be the wording?", and one option from there is to do an online certification course. However since I have already done the course as part of my previous study, so I was wondering whether doing it again will serve any purpose. Any thoughts?
