Fake Job Candidates Are Passing Real Technical Interviews
After a strong candidate vanished at the offer stage, Arena is considering in-person onboarding to prove new hires are real.

20VC with Harry Stebbings · Arena CEO: There Will be a $100BN US Open-Source Model & Data is a Trillion Dollar MarketThe candidate looked perfectly normal. On a screen in front of Arena engineers, he said he wanted to be an infrastructure engineer, answered the technical questions, and kept passing.
The interviewers were not junior staff guessing at answers. Anastasios (Andy) Kyrtsos, the chief executive of the AI company Arena, said they were top, world-class engineers, and they thought the man was real and remarkably good.
That is what makes the account so unsettling. A person can show up live, perform well under questioning, and still not exist.
In this case, the turn came at the end. When Arena tried to hire the man, Kyrtsos said, there was nothing there. He put it bluntly: the person does not exist.
Kyrtsos said Arena is not alone. He said fake applicants are showing up elsewhere too, sitting through interviews and passing before vanishing when the job becomes real, though he offered no numbers beyond what Arena had seen.
Why anyone would do it is still speculation, and Kyrtsos was careful not to blame any one culprit. It could be corporate espionage, a nation-state attacker, or a cyber hacker trying to get access to data and code, he said. Another motive is double pay, holding several remote jobs at once, like the widely discussed case from about a year ago of a worker who collected four jobs and then talked about it on podcasts. Except here, Kyrtsos said, this person was not real. It was AI.
The experience has shaken how he hires. Kyrtsos said Arena is considering making all onboarding in person. New hires would have to come to the office, meet in person, and show they are real before getting a computer. He noted that Figma already does this.
Questions people ask
How can a fake candidate pass a live technical interview?
Kyrtsos did not explain exactly how it was done. He said only that the candidate was not real and described it as AI. One possibility is that hidden software supplies the answers while a generated face and voice appear on screen, which would explain why fluent answers alone do not prove a person is real.
How common is this kind of hiring fraud?
Kyrtsos offered no numbers and pointed only to Arena's experience when he said it is happening elsewhere. There is no single public count that isolates live AI candidates. What is better documented is hiring fraud in remote hiring, where real people use false identities to win jobs, sometimes to collect multiple paychecks or to gain access to systems.
What can companies do besides requiring in-person onboarding?
Many companies now verify government ID, check employment history and references, and require a verified work location before sending equipment. Others add live checks that are hard to fake, such as asking a candidate to move on camera or solve an unfamiliar problem on a shared screen. No method is foolproof, so firms usually layer several checks.
