There is no need for this degree of obfuscation.

Put simply, organizations needing skilled personnel can delegate post-application screening to their set of approved staffing firms. Said organizations can employ initial screening techniques to filter out obvious fraud, such as requiring online applicants prove they possess the email/cell phone provided via industry standard mechanisms (while employing deny-lists as applicable). Given the remuneration commitment each hire represents year-over-year and the ability to hold staffing firms accountable, their fees are typically quite reasonable.

Why you introduced the question "what impact have LLMs had on productivity?" in this context escapes me.
