There is a documented case of a job applicant using deepfake technology to conduct a convincing interview for 70 minutes before being caught. That case is often cited as evidence of how sophisticated fakes have become. However, the more significant insight is what had already occurred before the interview began.

By the time the recruiter was 70 minutes into the interview, the fraudulent candidate had already passed a resume screen, cleared early screening, and advanced through multiple rounds to reach that stage. Every checkpoint in the hiring process had been passed. The interview was simply where the fraud was finally detected, after it had already cleared all the intended safeguards.

What the Hiring Funnel Actually Verifies

Most hiring processes include several stages designed to narrow the candidate pool. However, very few of these stages, before a background check, actually verify the candidate's identity.

• ​Resume screen: Evaluates fit.
• ​Phone screen: Evaluates communication.
• ​Technical assessment: Evaluates skill.

None of these confirm that the person completing them is who they claim to be. A synthetic identity built from stolen personal data (a real name, a real work history, an AI-generated face) is specifically constructed to pass each of these stages.

Background checks, which are the closest thing most organizations have to identity verification, occur late in the process. They come after phone screens, after multiple interview rounds, and after a candidate has been shortlisted and a hiring manager has invested significant time. According to LinkedIn's recruitment data, the average time-to-hire in the U.S. is between 36 and 44 days from posting to offer. The average recruiter spends about 23 hours screening resumes for a single hire. By the time a background check is conducted, the organization has already invested heavily in a candidate based entirely on unverified identity.

Moreover, background checks verify history, not identity. A fraudster using a stolen identity with a fabricated or borrowed work history can still pass one.

Proof's research indicates that building a convincing fake candidate can cost as little as $20 and take just 20 minutes. That investment produces a candidate who can clear every stage of the funnel that does not explicitly verify identity—which, in most hiring processes, means every stage until the background check.

Verify Candidates Anywhere in Your Workflow

The 70-minute interview case demonstrates the need for verification before the interview even begins. More broadly, verification should not be confined to a single stage. It is most effective when layered, fitting into the moments that matter most for your process, roles, and risk profile. Here’s what verification can look like at each stage:

At the Application Stage

Passive identity screening at the moment a candidate enters the pipeline can catch fraud signals in the application data itself: synthetic identity patterns, high-risk contact data, and behavioral anomalies that indicate automated or coordinated submissions. This occurs before any recruiter time is spent, removing fraudulent applications before the 23-hour screening clock starts.

At the Shortlist

When a candidate reaches the shortlist, government ID verification and liveness checks confirm that a real human is applying and matches the identity on file. This verification creates a record that persists through every subsequent stage. When the same candidate appears in an interview two weeks later, the question becomes whether the person on the call matches the previously verified identity.

At Offer and Day One

Verification should continue after the interview. A trained identity agent joining the pre-offer session brings the full context built across prior stages and runs real-time deepfake detection in the background. The I-9 process on Day One finalizes the record: a fraudulent hire cannot match the identity they used during a live document review conducted by a trained examiner.

A fraudster who cleared a 70-minute interview did so because nothing earlier in the process asked who they were. That is the gap that needs to be closed.
