Don’t take it personally, applying for a job is a game of chance as much as a game of merits. It’s simply a numbers game and luck whether your resume even gets looked at in the first place, even if you’re résumé how all their keywords. Hundreds, maybe thousands, of other resumes also hit their keywords.

If you’re lucky enough to get through the first sifting and get an interview with the hiring person (not an HR screener who doesn’t know anything about the job), then you can ask and maybe get a response on how you could have improved. (Don’t ask why you weren’t hired.)
