How to Spot Interview Fraud Before You Hire Someone Who Can't Do the Job
Interview fraud is happening more than you think—7% of candidates admit to it. Someone else takes the technical interview, the real candidate shows up on day one, and suddenly they can't do basic tasks they "aced" during screening.
Remote interviews made this easier to pull off, but you can catch it if you know what to look for. Here's how to protect yourself without turning your interview process into a TSA checkpoint.
Red Flag #1: Performance Varies Wildly Between Interview Rounds
What it looks like: Candidate crushes the technical screen but struggles with basic questions in the behavioral interview. Or vice versa.
Why it matters: Different people interviewing for them across different rounds. The technical expert handles tech screens, but can't answer culture fit questions.
What to do: Have the same interviewer (or panel) conduct at least two rounds. Consistency in knowledge and communication style across interviews is a good signal.
Red Flag #2: Camera Issues That Never Get Fixed
What it looks like: Camera is always "broken," positioned strangely, or mysteriously stops working mid-interview across multiple calls.
Why it matters: Makes it easier to have someone off-camera coaching or taking over entirely.
What to do: Make camera participation mandatory for all rounds. If someone can't get their camera working after two attempts, they're either technically incompetent (bad for a technical role) or hiding something (bad for any role).
Exception: Candidates with legitimate accessibility needs. But that should be communicated upfront, not discovered during the interview.
Red Flag #3: Long Pauses Before Every Answer
What it looks like: Candidate pauses 5-10 seconds before answering even simple questions. Responses sound rehearsed or like they're being read.
Why it matters: They might be receiving answers through an earpiece or waiting for someone off-camera to feed them responses.
What to do: Ask follow-up questions that require spontaneous thinking. Don't just stick to your script. If they nail the prepared questions but can't handle "Can you elaborate on that?" or "Give me a specific example," something's off.
Red Flag #4: Communication Style Changes Between Written and Verbal
What it looks like: Their emails are polished and technical, but verbal communication is poor. Or they write poorly but speak impressively well.
Why it matters: Different people might be handling different communication channels.
What to do: Pay attention to consistency across email, phone screens, video interviews, and written assessments. Big discrepancies warrant investigation.
Prevention Tactic #1: Identity Verification (Do It Early)
Frame it professionally: "Before we begin, I need to verify your identity for our records. Can you hold up a government-issued ID to the camera?"
Most legitimate candidates won't mind. Fraudsters will scramble or drop out.
Bonus: Use identity verification platforms that match photo IDs with video participants using biometric analysis. This isn't paranoid—it's smart risk management when hiring remote workers.
Prevention Tactic #2: Live Skills Validation (Not Just Take-Home Tests)
The problem: Take-home coding challenges or project assignments can be outsourced. Someone else does the work, submits it under the candidate's name.
The fix: Always follow up take-home work with live validation. Have them walk through their solution, explain their thinking, or make a small modification live.
Example for developers: "Great project. Can you open it up and show me how you implemented [specific feature]? Now can you modify it to do X instead of Y?"
If they can't navigate their own code or explain their approach, they didn't write it.
Prevention Tactic #3: Consistent Interview Panel
Why it works: Same interviewers across multiple rounds can spot inconsistencies in knowledge, communication style, and behavioral responses.
How to implement: Have at least one interviewer participate in both the technical and behavioral rounds. They'll notice if the candidate seems like two different people.
Prevention Tactic #4: Ask Unscripted Follow-Ups
The approach: Don't just run through your list of prepared questions. Ask follow-ups based on their answers.
If they mention working with Python: "What version? What libraries did you use most? Walk me through a specific problem you solved."
Fraudsters prepare for common interview questions. They don't prepare for deep dives into their supposed experience.
Prevention Tactic #5: First Week Skills Check
The reality: Even with good vetting, some fraud slips through. Catch it in the first week, not the first month.
How: Quick practical assessments during onboarding. Not extensive testing—just basic confirmation that they can do what they claimed.
For developers: Pair programming session on day 2-3. For analysts: Review a dataset and present findings. For sales: Role-play a discovery call with a manager.
If someone "aced" the technical interview but can't do basic tasks during onboarding, you caught fraud. Better to discover it in week one than week twelve.
What to Do When You Catch Fraud
Document everything. Save interview recordings, transcripts, and notes. If someone committed fraud during the interview process, you'll need evidence.
Terminate immediately. This isn't a performance issue you coach through. Fraud during interviews is grounds for immediate termination. Check with legal, but don't drag it out.
Consider reporting. Depending on severity and your legal team's advice, you might report to authorities. Interview fraud is becoming a bigger problem and repeat offenders exist.
Learn from it. What signals did you miss? How did they get through your process? Adjust your vetting to prevent it next time.
The Balance: Verification Without Paranoia
You don't want to treat every candidate like a criminal. Most people are honest and legitimate. But the 7% who aren't can cause serious damage—bad hires, team disruption, wasted time, lost money.
The goal: Simple verification steps that catch fraud without alienating real candidates.
Good verification:
- Camera-on requirements (standard in 2025)
- ID check before final interviews (quick, professional)
- Live skills validation after take-home work (reasonable)
- Consistency checks across interview rounds (smart process)
Bad verification:
- Interrogating candidates about why their camera positioning looks weird
- Requiring extensive background checks before initial interviews
- Treating every pause as suspicious
- Making candidates feel like you don't trust them
Verify professionally, catch fraud early, move good candidates through quickly. That's the balance.
The Bottom Line
Interview fraud is real, it's growing, and remote work makes it easier. You can catch it with:
✅ Camera-mandatory interviews ✅ ID verification before technical/final rounds ✅ Live skills validation after take-home work ✅ Consistent interviewers across rounds ✅ Unscripted follow-up questions ✅ First-week skills checks
That's the tip. Use it.
