TLDR
Interview cheating isn't an edge case anymore. It's mainstream. We analyzed 19,368 AI-powered interviews between July 2025 and January 2026, and the numbers tell a story that every hiring manager needs to hear.
Here's what we found:
38.5% of all candidates show signs of using AI assistance during interviews. Not "might be cheating." Actually detected cheating.
Technical roles are getting hit the hardest. 48% cheating rate compared to just 12% in sales positions.
Most cheaters pass your interviews. 61% score high enough to get hired if you don't have detection systems in place.
The problem tripled overnight. Between July and September 2025, cheating rates jumped 3x.
Your screen sharing software can't see it. Tools like Cluely and Interview Coder use invisible overlays that bypass video encoding completely.
Junior candidates cheat at nearly double the rate of senior professionals.
Traditional proctoring is dead. Browser lockdowns and tab switching detection don't work anymore.
The interview that wasn't real
You're halfway through a technical interview. The candidate has answered every question flawlessly. Their explanations are structured, detailed, and delivered with textbook precision.
But something feels off.
Every response comes exactly 4 seconds after you finish speaking. The candidate's eyes move in horizontal sweeps across their screen. Their vocabulary suddenly includes terms that seem too advanced for their experience level.
You're not interviewing a candidate. You're interviewing their AI assistant.
This isn't hypothetical anymore. We just analyzed 19,368 interviews conducted between July 2025 and January 2026. More than one in three candidates are using some form of AI assistance during live interviews. That's not hiring managers suspecting it. That's actual detection data confirming it.
Gartner says that by 2028, one in four candidate profiles will be completely fake. The tools enabling this have evolved from janky browser extensions into polished SaaS products marketed as "interview co-pilots" and "confidence boosters."
I'm going to break down how this actually works, why your current defenses probably aren't working, and what the data tells us about who's cheating and how to stop them.
Why 2026 became the year of interview fraud
Between July and September 2025, cheating rates tripled. Not a gradual increase. An explosion.
Two things happened at once.
First, the tools became invisible. Early cheating methods were clunky and risky. Modern tools like Cluely and Final Round AI use invisible screen overlays and audio pipelines that bypass every traditional detection method. Screen sharing? Useless. Browser lockdowns? Irrelevant. These tools operate below the application layer.
Second, the stigma disappeared. AI assistance has become normalized. When your competitors are using ChatGPT for daily work tasks, the mental barrier to using it in interviews drops significantly. Add viral TikToks showing people landing $150k jobs "with a little help," and you've got a FOMO-driven adoption wave.
The economics make perfect sense from a candidate's perspective. A $20-30/month subscription to a cheating tool is nothing compared to a six-figure engineering salary. It's not even about ethics anymore for many candidates. It's game theory. They assume everyone else is doing it, so not cheating puts them at a disadvantage.
For employers, the costs are brutal. A single bad hire can cost over $50,000 in direct losses. Add in the damage to team morale, delayed roadmaps, and the fact that the average time-to-fill for a tech role is 42 days, and you're looking at hundreds of thousands of dollars in total liability. Restarting a search after discovering fraud means critical positions stay vacant for months.
The cheating methods candidates actually use
Modern cheating isn't about opening a second browser tab. It's way more sophisticated. Based on detection data from thousands of interviews, here's what candidates are actually doing.
Invisible screen overlays (45% of cheaters use this)
Tools like Cluely and Interview Coder use low-level graphics hooks to render a transparent heads-up display directly over the candidate's screen. When they share their screen via Zoom or Teams, the video encoding captures only the desktop beneath the overlay.
The candidate sees AI-generated answers floating over their coding environment. The interviewer sees a pristine code editor with no trace of assistance.
This method dominates because it's nearly undetectable through traditional screen sharing. The overlay exists only on the local display. It never enters the video stream.
Voice mode LLMs (34% of cheaters use this)
For behavioral interviews, candidates are increasingly using ChatGPT or Gemini's voice mode. Here's the workflow:
The cheating tool captures the interviewer's voice through virtual audio drivers. This audio gets transcribed in real time, fed into a large language model, and converted into structured responses.
The entire loop, from question to answer appearing on screen, takes 1-2 seconds. Candidates stall with phrases like "That's an interesting question about..." while waiting for their script to appear.
Some candidates keep a phone or tablet just below the webcam's field of view, running the voice assistant continuously. They're literally reading responses off their phone while appearing to maintain eye contact.
Tab switching and second screens (18% of cheaters use this)
These traditional methods still exist but have declined dramatically. Candidates have learned these are easily flagged, so they've migrated to purpose-built cheating software.
Getting help from a friend (3% of cheaters use this)
Live help from another person has become rare. It requires coordination, introduces lag, and isn't faster or more reliable than automated tools.
Detection methods that actually work
Traditional proctoring is dead. Browser lockdowns, tab switching detection, and single-camera monitoring have been completely bypassed by modern tools. Companies that want to protect their hiring process are shifting to behavioral intelligence. Here's what works.
Watch for the lag loop
This is the most reliable indicator. When using AI tools, candidates show consistent 3-5 second delays after every question, regardless of difficulty.
Think about how you actually talk. You answer "How are you?" instantly but pause for several seconds on a complex technical question. Response timing varies naturally based on cognitive load.
AI-assisted candidates show a flat delay pattern. Every question gets the same 3-5 second lag: audio capture, transcription, LLM processing, candidate reads answer. This mechanical consistency is statistically impossible for genuine human responses.
Track eye movements
Human eyes move differently when remembering versus reading.
When you're recalling information, your eyes drift upward or to the side. When you're reading from a hidden script, your eyes move in straight horizontal lines from left to right, then snap back to the start of the next line.
This mechanical, rhythmic eye movement is a dead giveaway that someone is reading from an invisible overlay or secondary device. Reading also suppresses natural blink rates, which makes gaze tracking one of the most reliable detection signals.
Ask about fake technologies
Some companies now include questions about technologies that don't exist.
An AI tool, lacking the ability to verify reality in real time, will confidently hallucinate methods and syntax for fake libraries. A genuine candidate will search for documentation, find none, and ask clarifying questions.
The difference in response patterns is stark. Real candidates show curiosity and uncertainty. AI-assisted candidates provide confident, detailed answers to questions that have no real answer.
Make interviews unpredictable
Static assessments are vulnerable because they're predictable. The cheating tools are trained on standard interview questions. LeetCode problems, STAR method responses, common system design scenarios.
Adaptive interviews break this pattern. When a candidate provides a perfect textbook answer, drilling down with follow-up questions like "Can you tell me about a specific time that approach failed in your work?" forces them off-script.
AI tools struggle with this context switching. They can't maintain coherence when forced to pivot between domains or generate specific negative personal experiences. The candidate gets exposed when they can't provide authentic details.
How Fabric catches cheaters
Fabric takes a different approach than traditional proctoring. Instead of flagging binary events like tab switches, it treats each interview as a signal-rich data stream and analyzes over 20 distinct behavioral, technical, and linguistic signals.
Reading the subtle signals
The platform tracks gaze patterns to identify reading behavior, analyzes voice stress for deception indicators, and monitors head pose variance. One of the most telling signals is blink rate suppression. When someone is reading rather than thinking, their blink patterns change in measurable ways.
For deepfake detection, Fabric measures lip-sync latency. The millisecond drift between audio and video that's typical of synthetic video wrappers.
Technical fingerprints cheating tools can't hide
Fabric monitors technical signals that are nearly impossible to fake:
Keystroke dynamics. Humans type at varying speeds with natural pauses for typos and thinking. Burst typing, where large blocks of code appear at a perfectly steady rhythm, gets immediately flagged as non-human input.
Clipboard analysis. Detecting when code gets pasted from external sources.
Focus loss events. The window blurs for fractions of a second as overlays update. Imperceptible to humans but detectable by software.
Language pattern analysis
Fabric compares the complexity of spoken answers against the candidate's resume baseline. If a junior developer suddenly uses highly advanced technical terminology but can't explain those terms when pressed, the system flags the inconsistency.
The platform also identifies LLM-typical phraseology. Responses that start with "There are three main points to consider" or follow rigid, list-like structures that AI-generated content tends to use.
Conversational interviews that break the script
This is where Fabric really stands out. When a candidate provides a perfect textbook answer, Fabric's AI interviewer immediately pivots with follow-up questions that require genuine experience.
"Can you tell me about a specific time you applied that in a project and it failed?"
This context switching breaks the coherence of cheating tools. LLMs struggle to maintain context when forced to generate specific negative personal experiences or pivot between technical domains. The candidate is forced off-script, revealing their authentic capabilities.
Based on extensive evaluations across thousands of interviews, Fabric detects cheating in 85% of cases and provides timestamped reports with full root cause analysis for verification.
What 19,368 interviews taught us about cheating
Let's talk about what the numbers actually reveal. This isn't speculation. This is analysis from 19,368 real interviews with automated cheating detection running on every single one.
The cheaters are passing your interviews
61% of flagged cheaters score above pass thresholds. Think about that for a second. Without a separate cheating detection system, more than half of all cheaters would advance through your hiring process based on interview performance alone.
Why does this happen? Because AI models are trained on the exact same documentation and textbooks that hiring managers use to create scoring rubrics. The AI generates the textbook-perfect answer that interviewers are conditioned to look for.
Having the answer displayed on screen also eliminates the stuttering and nervousness typical of difficult questions. This artificial smoothness boosts communication scores, helping cheaters pass soft-skill checks.
Technical hiring is under siege
Technical roles face a 48% cheating rate compared to just 12% in sales positions. That's a 4x difference.
Why such a massive gap? Two reasons.
Tech candidates are more tech-savvy. They're more likely to discover and adopt new tools.
Technical questions are easier to cheat on. Coding problems and system design have more objective answers that AI can generate. Sales, marketing, and HR interviews rely more on open-ended questions about soft skills. Much harder for AI to fake convincingly.
Within technical roles, no specialization is immune. Frontend, backend, DevOps, data science. All show elevated cheating rates.
Junior candidates are cheating at double the rate
Candidates with 0-5 years of experience are significantly more likely to use AI assistance than senior candidates.
The entry-level market is saturated. Junior candidates often feel they need every possible advantage just to get noticed. Unlike senior engineers who might use AI to speed up syntax they already know, junior candidates often use AI to generate answers for concepts they've never actually learned.
Companies keep demanding unrealistic knowledge expectations from junior roles. Interview cheating becomes the workaround.
30% of repeat candidates always cheat
Among candidates who interviewed multiple times, 30% cheated in every single interview they took. These aren't desperate people making a one-time mistake. This is a deliberate strategy.
Another 23% are situational cheaters. They might cheat for dream jobs but interview honestly for backup options. Only 47% of repeat candidates never cheat.
Sunday is statistically the worst day to interview
Sunday interviews show a 47.1% cheating rate compared to 35-40% on other days.
Weekend interviews often happen from home with fewer distractions or observers. Candidates have more freedom to set up cheating tools, use secondary devices, or speak answers aloud without concern.
Lower salary bands have higher cheating rates
There's a clear downward trend. Candidates in lower salary bands cheat at higher rates.
This makes sense. Most of these roles are junior positions, which we already know have elevated cheating rates. Candidates in this bracket also tend to apply to hundreds of roles, using AI tools to mass-interview efficiently. It's a numbers game for them, not a curated career move.
Where we go from here
The interview cheating landscape has fundamentally changed. What was once a desperate act by a few bad actors has become a polished industry with subscription pricing and premium tiers.
The data from nearly 20,000 interviews makes this crystal clear. Cheating is widespread (38.5% of all candidates). It's concentrated in technical and junior hiring. And it's effective enough that most cheaters pass traditional interviews without detection.
Traditional countermeasures have been rendered obsolete. Browser lockdowns, tab switching detection, single-camera proctoring. All defeated by invisible overlays and secondary device configurations. The question is no longer "Can this candidate code?" but "Is this candidate real?"
Companies that want to protect their hiring process need to shift from passive proctoring to active behavioral intelligence. Analyzing timing patterns, gaze movements, language consistency, and interview dynamics. Not just watching for obvious red flags.
The first step is acknowledging that fraud detection is now a necessary component of recruitment infrastructure. The cost of ignoring this problem, bad hires, wasted interviewer time, delayed roadmaps, far exceeds the investment in proper detection.
If you're hiring at volume, especially for technical roles, the numbers suggest you should assume at least one in three candidates is getting external help. Without detection systems in place, you're essentially hoping for the best while your competitors are already adapting.
FAQ
Are these cheating tools really invisible to screen sharing software?
Yes. Modern tools like Cluely and Interview Coder use low-level graphics hooks to render overlays that exist only on the local display. They bypass the video encoding that screen sharing software captures. Based on our detection data, 45% of all cheating cases now use these invisible overlay methods.
What's the single most reliable sign someone is using AI during an interview?
Consistent response timing regardless of question difficulty. Genuine candidates answer easy questions quickly and harder questions more slowly. Cheaters using AI tools show a flat 3-5 second delay after every question. That's the time needed for audio capture, transcription, AI processing, and reading the response.
Which types of roles have the highest cheating rates?
Technical roles face a 48% cheating rate compared to 12% in sales positions. Within technical roles, no specialization is immune. Frontend, backend, DevOps, and data science all show elevated rates. Junior candidates (0-5 years experience) cheat at nearly double the rate of senior candidates.
Do traditional proctoring methods still work against AI cheating?
No. Traditional methods like tab switching detection and browser lockdowns have been largely defeated. Our analysis of nearly 20,000 interviews shows that 79% of cheating now happens through methods designed to be undetectable by traditional proctoring. Invisible overlays (45%) and voice mode LLMs (34%). Modern cheating tools operate beneath the application layer and can push answers to secondary devices that proctoring software cannot monitor.
What is Fabric?

The platform identifies AI-assisted responses through gaze tracking, response timing analysis, and content integrity checks. Based on extensive evaluations, Fabric detects cheating in 85% of cases with timestamped evidence.
How does Fabric detect cheating differently than other tools?
Unlike traditional proctoring that flags binary events like tab switches, Fabric uses behavioral analysis and dynamic interview formats. The conversational AI adapts based on responses, asking follow-up questions that force candidates off-script where cheating tools cannot help them. Fabric analyzes over 20 signals including gaze patterns, keystroke dynamics, voice stress, and language patterns to construct a comprehensive integrity score.
How many candidates are actually cheating in interviews right now?
Based on our analysis of 19,368 interviews conducted between July 2025 and January 2026, 38.5% of all candidates showed signs of using AI assistance during interviews. This rate jumped 3x between July and September 2025, indicating cheating has become a structural problem in hiring rather than an edge case.
What should I do if I suspect a candidate cheated?
Review behavioral signals like response timing consistency and eye movement patterns. Ask unexpected follow-up questions that require genuine experience to answer. Something like "Can you tell me about a time that approach failed in your work?" If you're using an AI interview platform, review the timestamped cheating detection reports and look for patterns like mechanical reading eye movements, unvarying response delays, or LLM-typical language structures.
