HackerRank is a popular platform for testing coding skills. Companies use it to screen job candidates. With AI tools like ChatGPT, many wonder: can HackerRank detect if someone uses ChatGPT to solve coding problems? This article answers that question. It explains HackerRank’s detection methods, ChatGPT’s abilities, and what candidates should know. All facts are up-to-date as of July, 2025.
How Does HackerRank Detect Cheating?
HackerRank uses advanced tools to catch cheating, including the use of AI like ChatGPT. Here’s how:
- AI-Powered Plagiarism Detection: HackerRank’s machine learning system analyzes coding patterns. It checks for signs of AI-generated code. It has a 93% accuracy rate, even catching manually typed ChatGPT solutions.
- Proctoring Features: Webcam monitoring, screen recording, and tab-switching detection track candidate behavior.
- Code Similarity Checks: HackerRank compares your code to others’ submissions. Identical or near-identical code raises red flags.
These methods make it hard to use ChatGPT without getting caught.
Table: HackerRank’s Detection Methods
| Method | Description |
|---|---|
| AI Plagiarism Detection | Spots AI-generated code patterns. |
| Proctoring Tools | Monitors webcam, screen, and tabs. |
| Code Similarity | Flags copied or similar code. |
Can ChatGPT Solve HackerRank Problems?
ChatGPT can solve many HackerRank problems, especially easier ones. It handles basic algorithms, loops, and array tasks well. However, it has limits:
- Complex Problems: ChatGPT struggles with niche or creative challenges requiring deep logic.
- Efficiency: Its solutions may not be optimal, failing strict time or space constraints.
- Errors: Tests show ChatGPT’s code can have syntax or logic flaws, needing human fixes.
For example, in a test of a “Validating Postal Codes” problem, ChatGPT needed corrections for a regular expression. Candidates using ChatGPT risk failing if they don’t understand the code.

Why Using ChatGPT to Cheat Is Risky
Using ChatGPT to cheat on HackerRank tests is not only detectable but also risky:
- Detection: HackerRank’s AI flags suspicious behavior, like rapid submissions or unusual coding patterns.
- Reputation Damage: Cheating can lead to bans from HackerRank or rejection by employers.
- Interview Failure: Even if you pass the test, follow-up interviews often expose gaps in knowledge.
Honesty is the best approach. Cheating may get you through one round but hurts long-term success.
How Are Employers Adapting to AI?
Companies know AI tools like ChatGPT are here to stay. They’re changing how they test candidates:
- Creative Questions: Employers design problems needing unique solutions AI can’t easily provide.
- Real-World Tasks: Some use project-based tests to mimic actual job challenges.
- Code Reviews: Candidates may be asked to review AI-generated code, testing critical thinking.
These changes make it harder for AI to give an unfair edge.
Tips for Candidates Using HackerRank
To succeed on HackerRank, focus on building real skills:
- Practice Regularly: Use HackerRank or LeetCode to improve coding.
- Use AI Wisely: ChatGPT can help you learn concepts or debug code, not solve tests.
- Understand Solutions: Don’t just copy AI code. Learn how it works to explain it in interviews.
- Stay Ethical: Cheating risks your career. Show your true abilities.

The Future of Coding Tests
AI is changing how coding skills are tested. Here’s what’s coming:
- AI-Friendly Assessments: Some platforms may allow AI use, testing how candidates work with tools.
- Focus on Skills: Tests will value problem-solving over rote coding.
- Continuous Updates: Platforms like HackerRank will keep improving detection to stay ahead of AI.
Candidates should prepare for a world where AI is part of the job, not a cheat code.
Conclusion
HackerRank can detect ChatGPT use through AI-powered tools, proctoring, and code analysis. While ChatGPT can solve some problems, it’s not foolproof and risks detection. Employers are adapting with smarter tests, and candidates should focus on real skills. Use AI to learn, not cheat, to succeed in coding interviews.
