Any leads on legit ATS cracking resume service?

I have been working in HRTech space for quite a few years now and never saw a guy whose application didn't get into ATS because his/her resume was not compliant. Generally ATS uses third party service to generate matching scores which takes keywords from your resume and job description, however it does not impact your resume visibility. Many companies and freelancers monetize on this vulnerability which is totally sham!

Hi all, Which website you use to check your ATS score

I have been applying for BIA positions or Business analyst positions but my resume isn't getting shortlisted in good companies. I am currently a Business analyst working in a FAANG company already and have relevant work experience. I am assuming it's something to do with my resume being ATS friendly, i tried making it as friendly as possible for ATS but only getting calls from random small companies. Any HR professionals out here? please give some guidance what I should do to make my resume get shortlisted?

I've been applying for internships for the past 2 weeks. Just wanted to know if I'm getting it right, do companies use ATS to evaluate and reject candidates? I have been using my custom resume for getting a product design internship, but I have had zero luck so far. Should I make an ATS one? Some help would be appreciated :)
