Job applicant fraud check

Every application is enriched with IP and phone data; stated location is compared to real location, internet-based phone numbers are checked, and the applicant is rated no / moderate / high fraud risk. Recruiters get a Slack alert with review steps; results are logged in the ATS.

Building block of the AI recruiting pipeline.

1Is this my problem?

Remote roles now attract fake applicants, sometimes aiming to get into company systems.

You'll recognise this if…

Fake applicants on remote roles.
Location mismatches discovered late.
Recruiters screen bad applications.

Companies affectedCompanies hiring remotely at volume. Typical fit: 10 staff to 50 staff.

Cost of doing nothing (estimate)Roughly 2–5 hours a week of manual work stays on the team, and the work is done inconsistently.

2Is this solution worth it?

The sources describe how this is built but publish no hard results, so the figures below are our estimates.

Your ROI, with the assumptions shown

Prefilled with illustrative assumptions (4 h/week at $50/h, 60% automated, build $3,000). Change them to your numbers.

Time saved (estimate)2–5 h/week

Limits and when not to build it

Skip it if: Local, referral-only hiring.

A flag is a reason to review, never an automatic rejection.
Check local law on automated hiring decisions and data use.

3How does it work?

One small internal tool does this for you. The same job, before and after:

Before · by hand

New application: someone notices
Enrich IP + phone
Location mismatch, VoIP check
Risk rating with reasons (by hand)
Slack alert with review steps
Log in ATS

Maturity ladder

What each level adds. Most teams start at level 1 or 2 and climb. Highlighted: where this build sits.

Level 1Basic automation
Trigger: new application. Fixed rules then enrich ip + phone, location mismatch, voip check, slack alert with review steps. No AI involved.
Level 2AI-assisted
An LLM handles the judgement step (risk rating with reasons) and a person reviews every output before it is used.
Level 3Autonomous agent
The agent runs end to end on its own and only stops for exceptions. Recruiter reviews every flag.
Level 4Self-learning system
Becomes part of the ai recruiting pipeline: Each quarter, hiring outcomes and interviewer feedback are compared with the AI scores to check the criteria and look for bias.

Level 4 lives in the AI recruiting pipeline: 6 stages with a learning loop.
