I'm feeling so defeated.

I'm feeling so defeated. I have education and varied experience in two different legs of my industry. I admit that my resume looked jumpy because of my different skillsets that landed me various jobs, but they were necessary at the time, and I have now been trying to focus on just one of those two areas, as is definitely required. I am certified in my current role, have many of the skills and experience required, but not all bc different roles required different skills. I'm 52. I recently interviewed with what looked to be a woman in her long twenties, and the test I was given was passed "with high proficiency"; I got the sense during the interview that they did not know what to do with my background, asked very, very basic questions, and were happy (surprised?) that I knew the answers. Still, they decided not to pursue me as a candidate. I should say that the roles I'm looking for are entry level, because these certifications and experience are required for my new trajectory. I just saw the SAME job posted 6 days ago that I was rejected from last month. I do believe that the only skill I did not have that they required was working within their electronic health record. Seriously, it's not hard; it's data entry. I know this sounds jumbled, but I've streamlined my resume, but still feel that potential employers (who have much fewer credentials and experience that I do) simply do not know what to do with me. I am very conscious about how I come across, stating that I excel in some of the areas need for the job, but I'm entry level in others. I am humble, but confident in what I do bring to the table, I and have no problem taking direction from someone much younger, because I feel you can learn from any and every person you work with, just as I had no problem managing people older than I in the past. It's demoralizing. I'm literally looking for a job that pays 1/3 of what I made my last consulting gig...and no one will let me.
