I'm aware of the various "is a cover letter even/still necessary?" discussions, but where I am at, a cover letter is mandatory, unless I'm applying to the 1% of companies that have some kind of web "quiz" where they do ask all kinds of questions.
So obviously, just as with CVs, there's various information floating around on how to write the perfect cover letter. Not more than one page… Within the expected standards of a business letter… but not too conservative… You must attract the recruiters interest within this page… so you gotta be creative… yet stay formal… etc. and the latter points is where I got an idea/question:
Can I open a cover letter with something along the lines of "If you're looking for a perfect fit for your job description, you can save some time and move to the next application. But if you're interested in someone with some starting experience who would like to fully pivot into this field and would like to bring in some new ideas and perspectives, please read on."?
Or is that considered an absolute No-no?
The job in question is quite the long shot, so I'm OK with this being taken at face value and my application being discarded, but if I were the recruiter I would actually prefer this honesty over all the bland "I'm the perfect, innovative, flexible, durable, 100% magic candidate!!!!" cover letters that tell you absolutely nothing, besides the person being good at marketing itself. But as I am not recruiter, I don't have any idea if that might not break some unknown (to me) rules or if there is some psychological reason why you never ever should do that.
For the record: I'd say I fulfil about a third of their demands, I've got some skills and understanding of another third and the last third would be completely new to me.
EDIT: The job in question is a "data scientist" and I'm only a scientist that happens to work with data (don't we all?) but not with AI/ML (what they're asking about) and I'm from a very different field, but still in STEM. Hence I'm seeing a lot of stuff I easily can do or quickly learn, but also a lot of things I have no clue about.
