it's a lie/deceit, but I'm not convinced it's fraud. fraud is:
> intentional misrepresentation of material existing fact made by one person to another with knowledge of its falsity and for the purpose of inducing the other person to act, and upon which the other person relies with resulting injury or damage.
Everything is fine until "resulting injury or damage". You'd have trouble proving that a guy who falsely said he wrote parallel FizzBuzz with REST API on a 500-client kubernetes rack caused you any harm.
