Columbia University this week suspended a student after he was disciplined for selling an AI-powered tool that helped coding job applicants cheat their way through the job seeking process. Chungin Lee owns a startup that was selling Interview Coder, an AI tool that gave job candidates prompts that let them cheat on the technical parts of many coding job interviews—a process that’s supposed to separate out applicants by skill, to assess their suitability for developer jobs. AI now plays an increasingly important role in the job seeking process, and its use by recruiters, hiring managers and applicants alike, is making the job market “increasingly surreal,” the Washington Post argues .

Lee told Business Insider this week , before learning of his suspension, that his business was tracking toward $2 million in yearly revenues. He had seemingly made no effort to hide what he was doing, and reportedly shared a video of himself using the AI tool during an interview with Amazon last year. After that, someone reported him to his university and he was subject to a disciplinary process. Technically, Lee was suspended for a year not for selling his tool, but for publicly sharing a recording of a hearing and other documents relating to his disciplinary process, which violated an agreement Lee made with the university. Business Insider said Lee had checked the university’s policies before making and marketing his tool, and had verified it couldn’t be used by students to cheat on in-class work, though it did offer an AI boost that applicants used to cheat on job interviews.

Using AI for coder job interviews is contentious. They’re intended as tests of applicants’ technical abilities, to help verify that they can actually deliver the skills they promise on their resumes. This issue is doubly important in light of a troubling Microsoft report recently showed that many young coders don’t actually understand the inner workings of the code they produce, because of an overreliance on using AI tools to help them write the code in the first place. That coding job applicants may be using a tool like Lee’s to land themselves lucrative development work only highlights the depth of the problem companies now face when they try to recruit this type of talent.

But, as the Washington Post points out, it’s not just coders who are using AI as a kind of job application “cheat code.” In fact “many” people seeking work employ a host of different AI tools to help them game the system, from AI software that actually “generates application materials” like cover letters to assistants that can help someone “bluff” their way through interviews and systems that can apply to “hundreds of jobs in minutes.”
