After landing internship offers from Amazon, Meta and TikTok, computer science student Chungin “Roy” Lee has decided to move to San Francisco.
But he won’t be joining any of those companies.
Instead, Lee will be building his own startup that offers a peculiar service: helping software engineers use artificial intelligence to cheat in their technical job interviews.
“Everyone programs nowadays with the help of AI,” said Lee, a 21-year-old student at Columbia University, which has opened disciplinary proceedings against him, according to documents viewed by CNBC. A Columbia spokesperson said the university doesn’t comment on individual students.
“It doesn’t make sense to have an interview format that assumes you don’t have the use of AI,” Lee said.
Lee is at the forefront of a movement among professional coders who are exploiting the limitations of remote job interviews, popularized during the Covid pandemic, by using AI tools off camera to ensure they give hiring managers the best possible answers.
The hiring process that took hold in the work-from-home era involved candidates interviewing from behind a Zoom screen rather than traveling, sometimes across the country, for on-location interviews, where they could show their coding skills on dry-erase boards.
In late 2022 came the boom in generative AI, with the release of OpenAI’s ChatGPT. Since then, tech companies have laid off tens of thousands of programmers while touting the use of AI to write code. At Google, for example, more than 25% of new code is written by AI, CEO Sundar Pichai told investors in October.
The combination of rapid advancements in AI, mass layoffs of software developers, and a continuing world of remote and hybrid work has created a novel conundrum for recruiters.
The problem has become so prevalent that Pichai suggested during a Google town hall in February that his hiring managers consider returning to in-person job interviews.
Google isn’t the only tech company weighing that idea.
But engineers aren’t slowing down.
Lee has turned his cheating into a business. His company, Interview Coder, markets itself as a service that helps software developers cheat during job interviews. The internship offers that he landed are the proof he uses to show that his technology works.
AI assistants for virtual interviews can provide written code, make code improvements, and generate detailed explanations of results that candidates can read. The AI tools all work quickly, which is helpful for timed interviews.
Hiring managers are venting their frustrations on social media over the rise of AI cheaters, saying that those who get caught are eliminated from contention. Interviewers say they’re exhausted from having to discern whether candidates are using their own skills or relying on AI.
‘Invisible’ help
The cheating tools rely on generative AI models to provide software engineers with real-time answers to coding problems as they’re presented during interviews. The AI analyzes both written and oral questions and instantaneously generates code. The widgets can also provide the cheaters with explanations for the solutions that they can use in the interview.
The tools’ most valuable feature, however, might be their secrecy. Interview Coder is invisible to the interviewer.
While candidates are using technology to cheat, employers are observing their behavior during interviews to try to catch them. Interviewers have learned to look for eyes wandering to the side, the reflection of other apps visible on candidates’ glasses, and answers that sound rehearsed or don’t match questions, among other clues.
Perhaps the biggest tell is a simple “Hmm.”
Hiring managers said they’ve noticed that many candidates use the ubiquitous sound to buy themselves time while waiting for their AI tools to finish their work.
“I’ll hear a pause, then ‘Hmm,’ and all of a sudden, it’s the perfect answer,” said Anna Spearman, founder of Techie Staffing, an agency that helps companies fill technical roles. “There have also been instances where the code looked OK, but they couldn’t describe how they came to the conclusion.”
Henry Kirk, a software developer and co-founder of Studio.init in New York, said this type of cheating used to be easy to catch.
“But now it’s harder to detect,” said Kirk. He said the technology has gotten smart enough to present the answers in a place that doesn’t require users to move their eyes.
“The eye movement used to be the biggest giveaway,” Kirk said.
Interview Coder’s website says its virtual interview tool is immune to screen detection features that are available to companies on services such as Zoom and Google Meet. Lee markets his product as being webcam-proof.
When Kirk hosted a virtual coding challenge for an engineering job he was looking to fill in June, 700 people applied, he said. Kirk recorded the process of the first interview round. He was looking to see if any candidates were cheating in ways that included using results from large language models.
“More than 50% of them cheated,” he said.
AI cheating tools have improved so much over the last year that they’ve become nearly undetectable, experts said. Other than Lee’s Interview Coder, software engineers can also use programs such as Leetcode Wizard or ChatGPT.
Kirk said his startup is considering moving to in-person interviews, though he knows that potentially limits the talent pool.
“The problem is now I don’t trust the results as much,” Kirk said. “I don’t know what else to do other than on-site.”

Back to the Googleplex
It’s become a big topic at Google, and one Pichai addressed in February at an internal town hall meeting, where executives read questions and comments that were submitted by employees and summarized by AI, according to an audio recording that was reviewed by CNBC.
One question asked of management was, “Can we get onsite job interviews back?”
“There are many email threads about this topic,” the question said. “If budget is constraint, can we get the candidates to an office or environment we can control?”
Pichai turned to Brian Ong, Google’s vice president of recruiting, who was joining through a virtual livestream.
“Brian, do we do hybrid?” Pichai asked.
Ong said candidates and Google employees have said they prefer virtual job interviews because scheduling a video call is easier than finding a time to meet in available conference rooms. The virtual interview process is about two weeks faster, he added.
He said interviewers are instructed to probe candidates on their answers as a way to decipher whether they actually know what they’re talking about.
“We definitely have more work to do to integrate how AI is now more prevalent in the interview process,” said Ong. He said his recruiting organization is working with Google’s software engineer steering committee to figure out how the company can refine its interviewing process.
“Given we all work hybrid, I think it’s worth thinking about some fraction of the interviews being in person,” Pichai responded. “I think it’ll help both the candidates understand Google’s culture and I think it’s good for both sides.”
Ong said it’s also an issue “all of our other competitor companies are looking at.”
A Google spokesperson declined to comment beyond what was said at the meeting.
Other companies have already shifted their hiring practices to account for AI cheating.
Deloitte reinstated in-person interviews for its U.K. graduate program, according to a September report.
Anthropic, the maker of AI chatbot Claude, issued new guidance in its job applications in February, asking candidates not to use AI assistants during the hiring process.
“While we encourage people to use AI systems during their role to help them work faster and more effectively, please do not use AI assistants during the application process,” the new policy says. “We want to understand your personal interest in Anthropic without mediation through an AI system, and we also want to evaluate your non-AI-assisted communication skills. Please indicate ‘Yes’ if you have read and agree.”
Amazon is also taking steps to combat AI cheating.
The company asks that candidates acknowledge that they won’t use unauthorized tools during the interview or assessment process, spokesperson Margaret Callahan told CNBC.

‘F*ck Leetcode’
If you visit InterviewCoder.co, the first thing that greets you is large gray type that reads “F*ck Leetcode.”
Leetcode is the program used by many tech companies to evaluate software engineers for technical roles. Tech companies such as Meta, Google and Amazon use it to keep tabs on the thousands of job applicants they evaluate.
“Every time I mention interviews, I get frustrated comments about Leetcode,” wrote Ryan Peterman, a software engineer at Meta, in a newsletter posted on Substack in December. Peterman said Leetcode problems are purposely designed to be much harder than what software engineers would do on the job. Leetcode is the best tool companies have to filter hundreds of applicants, Peterman wrote.
Coders said they hate Leetcode because it emphasizes algorithmic problem-solving and asks applicants to solve riddles and puzzles that seem irrelevant to the job, according to those CNBC spoke with as well as comments CNBC found from engineers across various social media platforms. Another downside is that it sometimes requires hours of work that may not result in a job offer or advancement, they said.
Leetcode served as Lee’s inspiration for building Interview Coder, he said. With the help of AI, he said, he created the service in less than a week.
“I thought I wanted to work at a big tech company and spent 600 hours practicing for Leetcode,” Lee said. “It made me miserable, and I almost stopped programming because of how much I didn’t like it.”
Lee’s social media posts are filled with comments from other programmers expressing similar frustrations.
“Legend,” several comments said in response to some of his X posts. Others said they enjoyed him “f—ing with big tech.”
Rival software Leetcode Wizard was also inspired by distaste for Leetcode.
Isabel De Vries, Leetcode Wizard’s head of marketing, told CNBC in a statement that Leetcode-style interviews fail to accurately measure engineering skills and fail to reflect actual daily engineering work.
“Our product originates from the same frustrations many of our users are having,” De Vries said.
Leetcode did not respond to CNBC’s request for comment.

When Kirk, of Studio.init, posted on LinkedIn in February to vent about his frustrations with AI cheating, he received nearly 200 comments. But most argued that employers should allow candidates to use AI in the hiring process.
“Even the SAT lets you use a calculator,” said one comment. “I think you just make it harder to succeed on purpose when in the real world Google and gpt will always be at my fingertips.”
Lee promotes Interview Coder as being “invisible to all screen-recording softwares.” To prove its effectiveness, he recorded himself passing an Amazon interview and posted the video on YouTube. Amazon and the other companies that had made offers to Lee then rescinded them.
Lee got hundreds of comments praising the video, which YouTube removed after CNBC reached out to Amazon and Google for this story. YouTube cited a “copyright claim” by Amazon as the reason for removing the video.
“I as an interviewer am so annoyed by him but as a candidate also adore him,” former Meta staff engineer Yangshun Tay, co-founder of startup GreatFrontEnd, wrote in a LinkedIn post about Lee and his video. “Cheating isn’t right, but oh god I am so tired of these stupid algorithm interviews.”
After YouTube removed the video, Lee uploaded it once again.
Cheating as a service
Lee said he never planned to work at Amazon, Meta or TikTok. He said he wanted to show others just how easy it is to game Leetcode and force companies to find a better alternative.
And, he said, he’s making money in the process.
Interview Coder is available as a subscription for $60 a month. Lee said the company is on track to hit $1 million in annual recurring revenue by mid-May.
He recently hired the internet influencers who go by the name “Costco Guys” to make a video marketing his software.
“If you’re struggling to pass your Leetcode interviews and want to get a job at a big tech company, you’ve got to take a look at Interviewcoder.co to pass your interview,” the Costco Guys say in their video. “Because Interview Coder gets five big booms! Boom! Boom! Boom! Boom! Boooooom!”
Leetcode Wizard bills itself on its website as “The #1 AI-powered coding interview cheating app” and “The perfect tool for achieving a ‘Strong Hire’ result in any coding interview and landing your dream job at any FAANG company.” Leetcode Wizard charges 49 euros ($53) a month for a “Pro” subscription.
More than 16,000 people have used the app, and “several hundred” people have told Leetcode Wizard that they received offers thanks to the software, the company told CNBC.
“Our product will have succeeded once we can shut it down, when leetcode interviews are a thing of the past,” De Vries said.
Lee said he’s moving from New York to San Francisco in March to continue building Interview Coder and start working on his next company.
Kirk said he understands software engineers’ frustration with Leetcode and the tech industry. He’s had to use Leetcode numerous times throughout his career, and he was laid off by Google in 2023. He now wants to help out-of-work engineers get jobs.
But he remains worried that AI cheating will persist.
“We need to make sure they know their stuff because these tools still make mistakes,” Kirk said.
Half of companies currently use AI in the hiring process, and 68% will by the end of 2025, according to an October survey commissioned by ResumeBuilder.com.
Lee said that if companies want to bill themselves as AI-first, they should encourage its use by candidates.
Asked if he worries about software engineers losing the trust of the tech industry, Lee paused.
“Hmm,” he mumbled.
“My reaction to that is any company that is slow to respond to market changes will get hurt and that’s the fault of the company,” Lee said. “If there are better tools, then it’s their fault for not resorting to the better alternative to exist. I don’t feel guilty at all for not catering to a company’s inability to adapt.”

National Basketball Association superstar Russell Westbrook is taking a shot off the court at simplifying funeral planning with artificial intelligence.
The famed Denver Nuggets point guard on Wednesday announced the launch of Eazewell, a startup that uses AI technology to streamline the process for coordinating funerals. Westbrook founded the venture with former Charlotte Hornets star Kemba Walker and childhood friend Donnell Beverly Jr., who serves as president of Russell Westbrook Enterprises and CEO and co-founder of Eazewell.
“My whole career, on and off the court, has been about stepping up decisively in the moments that matter most,” Westbrook wrote in a statement to CNBC. Westbrook and the Nuggets are currently facing the Oklahoma City Thunder in the NBA Western Conference semifinals. “Eazewell is exactly that — a decisive solution to a very real problem.”
The Los Angeles-based company uses AI to curate funeral options catered to each user’s budgets and preferences. The platform assists with paperwork, budget planning, invitations and overlooked tasks such as canceling a deceased loved one’s utility bills and social media accounts. Eazewell currently has 11 employees and has already tested its beta platform with more than 1,000 families.
Eazewell has not disclosed funding but has revenue agreements with partner services. The startup is also working on partnerships with finance and life insurance companies in the space. The service is free to use and does not have an ads component “at this stage,” a company spokesperson said.
“We’re trying to take the weight off people’s shoulders as much as we can, and make this process so much easier for people,” Walker told CNBC in a phone interview. Walker played college basketball with Beverly at the University of Connecticut.

Learning from an early loss
Eazewell traces its origins to Westbrook and Beverly’s high school days, when their friend and basketball teammate Khelcey Barrs III passed away unexpectedly from an enlarged heart. Westbrook commemorates Barrs to this day by wearing a bracelet with the initials “KB3” in every NBA game he plays and on his signature Jordan Why Not Zer0.6 “Khelcey Barrs” shoe.
“It’s a reminder that life can change in an instant,” Westbrook said. “You don’t get to choose the moment, but you do get to choose how you respond.”
The experience left a lasting effect on the two friends, Beverly said, but it wasn’t until the death of Beverly’s parents that he experienced funeral planning hurdles firsthand. Beverly said the experience was “messy” and “grueling.”
Disillusioned and frustrated by the process after the death of his mother and father in 2016 and 2023, respectively, Beverly turned to his close friends to come up with the solution that became Eazewell.
“It just seems like the perfect time to really turn our shared pain into purpose,” Beverly said.

One of Eazewell’s most innovative features is its voice-activated AI agent that can gather cost quotes and call funeral homes on a user’s behalf.
Recent advancements in AI have only recently made it possible to automate tasks and create agents that can manage these jobs in an empathetic and compassionate manner, said Viviane Ghaderi, Eazewell’s tech chief and a former Amazon executive.
Stephen Stokols, an Eazewell investor and CEO of Tru Skye Ventures, an early-stage sports technology and wellness venture firm, said these “transformational” AI advancements helping bring the funeral industry out of the “dark ages” initially drew him to the project.
Walker said he hopes Eazewell can offer users the tools to navigate a topic that is not taught in school or early life.
“We know how important it is to have someone by your side to help with the details that come after a loss,” Westbrook said.

Uncertainty — that was the theme during earnings season for the world’s biggest semiconductor firms which are unclear on demand for their products as a result of changing U.S. tariff policy and export restrictions that have been place on China.
U.S. President Donald Trump’s “reciprocal” tariffs took effect in April though they were paused shortly after. The White House also exempted certain tech products such as smartphones and chips. However, the U.S. is investigating imports of semiconductor technology which could come under new duties.
Meanwhile, Washington last month added more semiconductor products from Nvidia and AMD to a list of items that are restricted for export to China, building on Biden-era curbs.
The changing tariff and China policy has caused consternation among executives at the world’s largest chip companies with visible impacts on their busiensses already.
AMD on Tuesday said that it expects $1.5 billion in lost revenue thorugh the end of its fiscal year as a result of AI chip export curbs to China, despite topping earnings estimates for the first quarter.
Super Micro issued disappointing guidance on Tuesday citing tariff and macroeconomic uncertainty. The company said it would not provide guidance for its fiscal year 2026 until “visibility” becomes clearer. The stock fell 4% in premarket trade.
And Marvell said on Tuesday that it is postponing its previously scheduled investor day from June 10 to a “future date in calendar 2026.” Shares of the firm fell 4.4% in premarket trade.
“We have decided to postpone our investor day given the current uncertain macroeconomic environment,” Matt Murphy, CEO of Marvell, said in a statement.
Clarity in ‘short supply’
Semiconductor stocks have been under pressure this year amid the growing macroeconomic uncertainty and trade policies from the U.S. There is also concern about the demand for AI products even as technology giants like Microsoft and Amazon continue to commit billions of dollars to build data centers.
The VanEck Semiconductor ETF, a basket of chip stocks, is down nearly 12% this year.
And it’s not just U.S. companies that are feeling the heat. Samsung said last month that “demand volatiltiy is expected to be quite high” as a result of tariff policy changes and macroeconomic uncertainty.
“Due to the rapid changes in policies and geopolitical tensions among major countries, it’s difficult to accurately predict the business impact of tariffs and countermeasures,” a Samsung executive said on the earnings call.
“There are a lot of uncertainties ahead of us.”
Samsung is one of the world’s largest memory chipmakers.
“The semiconductor sector is grappling with a complex mix of demand signals and geopolitical headwinds,” Ben Barringer, global technology analyst at Quilter Cheviot, told CNBC by email.
Barringer said that Marvell’s decision to postpone its investor day “adds a layer of uncertainty at a time when clarity is in short supply,” while Super Micro’s weak outlook also “raised eyebrows.”
“With macro uncertainty and export restrictions still looming large, the path ahead for chipmakers remains bumpy, even as underlying demand holds up in certain areas,” Barringer added.
Nvidia CEO: ‘Let us go race’
The U.S. chip industry has sought to show that it is leading in technology versus China and that it should be allowed to sell more product there.
Nvidia CEO Jensen Huang told CNBC on Tuesday that China will likely be a $50 billion artificial intelligence market in two-to-three years.
“It would be a tremendous loss not to be able to address it as an American company. It’s going to bring back revenues, it’s going to bring back taxes, it’s going to create lots of jobs here in the United States,” Huang said.
For the last few years, Washington under both Biden and Trump, have looked to use export restrictions to restrict China’s access to American technology in areas such as AI and semiconductors. This has prompted Chinese firms to ramp up focus on homegrown technology with companies like Huawei looking to create viable competing products to the likes of Nvidia.
Chinese companies such as DeepSeek and Alibaba have also been able to launch high-performing AI models.
Nvidia’s Huang said there is competition in AI right now but American firms should be able to compete with China.
“The United States has to recognize that we are not the only country in that race, that we have competitors. We are confident people, we are a confident country we have confident companies, we are not afraid of a race. We look forward to a race. Just let us go race,” Huang told CNBC.
“And so I think that now is the time when the United States needs to realize that we need to put the pedal to the metal … we’ve just got to go for it. Waiting around, talking about it, trying to hold people back is not necessarily the best move. The best move is let American do American, let us go after it and win it.”
