Coding interviews are broken
The current interview process is failing both companies and candidates
Imagine the following
You've spent weeks sending out job applications, you've studied data structures and algorithms for months, and you've practiced leetcode, completing both the Blind 75 and NeetCode 150. Finally, you feel ready.
After landing the interview, you get 45 minutes to prove your coding skills. It's going well until you're faced with a tough leetcode problem you have never seen before. You struggle to solve it, and the interview ends in disappointment.
Next day: rejection email. Sadly, this is the current state of the interview process for most engineers.
Leetcode ≠ Real job
Leetcode-style interviews fail to accurately measure engineering skills and don't reflect actual daily engineering work. This gamified approach is broken and a poor indicator of critical thinking skills.

Real success stories from developers who landed their dream jobs
"I was nervous about my Google interview, but Leetcode Ninja helped me solve a tricky graph problem in minutes. The solution was so well-explained that I could implement it naturally while explaining my thought process. It felt like having a senior engineer guiding me through the problem!"
Sarah
Software Engineer at Google
"During my Amazon interview, I used Leetcode Ninja on my phone while sharing my screen. The solution to the dynamic programming problem appeared instantly, and I could explain it confidently. The interviewer even complimented my approach! I wouldn't have passed without it."
Michael
Senior Developer at Amazon
"I was stuck on a complex binary tree problem during my Meta interview. Leetcode Ninja not only gave me the solution but also explained the time complexity and edge cases. I aced the interview and got the offer! The web view on my tablet was perfectly positioned next to my code editor."
Emily
Frontend Engineer at Meta
Frequently Asked Questions
How does Leetcode Ninja avoid detection?
- Blocking the ability to copy and paste
- Logging when you leave the browser tab
- Checking your webcam for suspicious eye movement
- Listening to your microphone input for suspicious noises
- Scanning your code for irregular patterns
- Checking for plagiarism in your final submission
We have taken several measures to avoid detection:
- Invisible to most screen-sharing software and screenshots
- Controlled by global, configurable hotkeys that run at a privileged level
- All AI output is humanized to prevent detection
- Can be placed anywhere on your screen (we recommend near your code editor)
As of January 2025, we have never been detected in our real interview tests by any coding platform.
I'm taking a proctored test where my screen will be recorded, how do I avoid detection?
- Share your camera, microphone, and screen
- Show government-issued photo ID
For proctored tests, we recommend:
- Opening our web view on a secondary device
- Putting our desktop application in hidden mode
- Placing the secondary device close to your code input to prevent suspicious eye movements
This approach guarantees 100% safety as some screen-sharing software can circumvent our desktop app's hidden mode.
