In my experience companies do not compare resumes with formal applications.
This applies where recruiters and hiring managers use resumes to evaluate candidates. I have yet to see a hiring manager reference data submitted in an application. The applications contain PII so they are should be access restricted. HR uses the application for background checks, past employment verification, and all the legal stuff.
A candidate formally attests to the accuracy of their application. What they exclude from their resume/story is as important as what they include.
The hiring manager does not have to know that you are currently unemployed and have been for a few months. If this is discovered just claim that your resume is outdated. Only an asshole employer will use your desperation to lowball or reject you, so dodge that bullet.
Fudge your employment dates. Exclude your past toxic employers from your story. Exclude jobs from your resume that you held for a short period of time. No need to explain why you noped out of a job or got fired after a few months. Exclude employment gaps, so no need to explain those either.
Impress hiring managers with your story. Let HR check its boxes to get the legal paperwork done.
My personal experience:
This worked with a job I held for several years that started with a cold-call recruiter contact. This worked for several referrals within small communities where everybody seemingly knows each other.
My job leads start with a resume review and a meeting with the hiring manager. The hiring manager only has my resume regardless of when I submit a formal application.
My resume reflects the work I am performing and the skills I possess. I include longer-duration jobs of which I am proud and can provide an honestly palatable reason for departure. It shows eight consecutive jobs over the last 26 years ( >3yr average) only describing start/end years. I held 13 different jobs in that timeframe (2yr average) so five <1yr failure-to-launch jobs and one voluntary employment gap are absent.
I have never had to justify those three months I took off after 9/11 when I abruptly quit without notice. I was justified IMO but employers dislike you sticking up for yourself because they look at their risk, not your reasons. I do not have to discuss why I quit some jobs after a few months because it was not working for everybody.
