The Free Candidate Fraud Signal Library

(60+ Flags to Catch Fraud Before It Enters Your Pipeline)

If you've ever finished an interview process and wondered if the candidate was actually who they said they were, this is for you. Free to download, free to share with your team.

Why we built this

For the past 7 years, we've been helping US companies hire engineers remotely from Latin America and Portugal.

At some point, candidate fraud stopped being a rare edge case and became part of almost every search we ran. Fake profiles, AI tools feeding answers in real time during live interviews, and proxy candidates where someone entirely different from the person you interviewed shows up to do the actual job.

We started documenting every signal our recruiters were catching. Before the interview, during it, and in the weeks after. We built it into an internal library that we use on every role we work on.

It now has 60+ signals, color-coded by severity and rated by how hard each one is to check. We're sharing it for free.

Here's What You'll Get:

60+ signals organized into three categories:

  • Before the interview — 53 signals covering identity, LinkedIn profile, digital footprint, employment history, and application behavior
  • During the interview — the 7 signals that matter most when you're live on a call

Remote hiring fraud is not going away. The tools candidates use are getting more sophisticated every year and most hiring teams are still catching up. The good news is that most fraud is detectable if you know what to look for.

That's what this library is for. Free to download, free to share, and ready to use on your next search.
