After being offered internships by Amazon, Meta, and TikTok, Chungin “Roy” Lee, a 21-year-old computer science student at Columbia University, decided to move to San Francisco, but not to accept the offers.

Instead, Lee started a startup, Interview Coder, that offers a unique service: helping software engineers cheat on technical interviews. The fact that he aced his interviews is a testament to the tool’s effectiveness.

Columbia University is looking to discipline Lee, according to CNBC .

Lee believes that everyone is programming with some AI these days. He is among a growing number of professional programmers looking to exploit the online interviewing craze, which has become more prevalent during the Covid-19 pandemic, by using AI tools to ensure the best possible answers.

Lee’s tool is based on generative AI models that can write code, edit code, and explain the results to candidates in detail. The AI ​​analyzes both oral and written questions and writes code on the fly. The process is fast and real-time.

Most importantly, the interviewer is completely unaware that the candidate is cheating. According to Interview Coder’s website, the tool is immune to the software detection features available on Zoom or Google Meet.

Since ChatGPT launched in late 2022, tech companies have laid off tens of thousands of programmers while boasting about using AI to code. For example, in October 2024, Google CEO Sundar Pichai told investors that more than 25% of the company's new code was written by AI.

CNBC commented that the combination of rapid advances in AI, a wave of mass layoffs, and a hybrid working world between physical and online has created a conundrum for employers.

They claim to disqualify candidates found to be cheating and also express exhaustion in determining whether candidates use AI or not.

The issue was so acute that Google employees raised it at a meeting in February, when Mr. Pichai suggested hiring managers return to in-person interviews, even though they were more time-consuming.

He also believes it will help candidates understand the company culture.

Detecting cheating is a real mind game. Interviewers look for signs like sideways eye movements, reflections in eyeglasses, or lingering hums.

There are times when a candidate gives a perfect answer but fails to describe the work process.

It’s getting harder to tell if someone is cheating, says Henry Kirk, a software developer and co-founder of Studio.init in New York. Technology has gotten smart enough that users don’t need to move their eyes to see the answer.

Kirk hosted a virtual programming challenge for engineers in June 2024. 700 people signed up, but in the first round of interviews, he said more than 50% cheated.

In addition to Interview Coder, software engineers also turn to programs like Leetcode Wizard and ChatGPT. Kirk is considering switching to in-person interviews, though he knows it will limit the pool of good people. “The problem is that I don’t trust the results as much as I used to,” he admits.

AI candidate fraud is a problem that “all of our competitors are looking at,” according to Brian Ong, Google’s vice president of recruiting. Other companies have changed their hiring processes to guard against it.

Deloitte is reintroducing face-to-face interviews for its graduate and apprenticeship programmes in the UK, according to a Financial Times article in September 2024.

Anthropic, the maker of the AI ​​chatbot Claude, issued new guidelines in February asking candidates not to use AI assistants during the hiring process. Amazon requires candidates to confirm that they are not using unauthorized tools during the interview and assessment process.

Despite the controversy among recruiters, Lee's tool has been well received by many. Hundreds of comments of praise have appeared under the Interview Coder promotional video.

“As an interviewer, I was furious, but as a candidate, I admired Lee,” former Meta engineer Yangshun Tay, co-founder of startup GreatFrontEnd, wrote on LinkedIn. “Cheating is not right, but I am tired of these stupid algorithm interviews.”

Interview Coder costs $60 a month. Lee says the startup is on track to make $1 million a year. Leetcode Wizard, meanwhile, charges $53 a month for its Pro version. More than 16,000 people use the app.

If companies want to advertise themselves as leaders in AI, they should encourage candidates to use AI, Lee said. Asked if he was worried about software engineers losing faith in the tech industry, the 21-year-old student mumbled.

“Any company that is slow to respond to market changes will be hurt, and that is their fault. If there are better tools, it is their fault for not switching to a better alternative to survive. I don’t see fault in a company’s lack of adaptability.”
