I did a similar thing on my CV/resume (when I still used one): for my interests, I'd just list everything I'd had some genuine interest in (shallow or deep), and added to it over months, so it was about 5-7 lines of words.

The purpose of this interests section was to form some non-work connection of interests with the interviewer. What happens if you look at a block of words like that is that your mind instantly picks out words that are meaningful to you.

It was an interactive, mind-reading resume.
