This Columbia student created an AI tool and got internship offers from Amazon, Meta

A student from Columbia University, Roy Lee, claims that he got summer internship offers from big tech companies like Amazon, Meta, TikTok, and more for creating an artificial intelligence (AI) tool. Lee, in a post on X (formerly Twitter) writes that he created the AI tool to help him during coding interviews. The tool, called Interview Coder, is a hidden app that helps solve coding and algorithm problems in interviews, like those on LeetCode.
In the post, Lee shared that he used Interview Coder to pass interviews and secure internship offers. He even showed a screenshot of his LinkedIn profile, showing internships at Meta, TikTok, Amazon, and Capital One starting in February 2025. He mentioned he would choose one internship if others were taken back.


Lee also posted a video on YouTube showing him using Interview Coder during a live Amazon interview. After the video gained attention, he shared an email that Amazon allegedly sent to Columbia University, complaining about his actions.
"Chungin, or Roy as he prefers, recently interviewed for our Amazon SDE Intern role in which he proved to be a strong candidate. Soon after, I received a link to a YouTube video created by Roy in which he showed himself using an invisible cheating tool to gain an unfair and unapproved advantage during the interview process. While this is disturbing enough, further research showed that Roy is selling this tool to other students and engineers, spreading the tool to many users," the email read.

Lee responded to the message, saying he had already turned down the offer and had no plans to work at Amazon. "Point of the software is to hopefully bring an end to Leetcode interviews. This tool took me a week to build and a better engineer could've built it in half a day," he wrote.
