Noted. I imagine systems like Lever or proprietary hiring platforms usually appear more with companies that have HR, whereas a few sentences for a position that only accepts application materials via email will go a lot further than a multi-section cover letter. I've been trying to stay away from making my cover letter feel too much like a form, but because I'm shorter than most on experience, I feel like it's important to explain myself a bit in the cover letter, but, if it never gets read, it's kind of a moot point anyway. I've thought about switching up my resume depending on the position, but I don't really have a big collection of tools to showcase quite yet so I'm thinking its current permutation is more or less complete.
Thanks so much for your feedback!
