HackerRank's Tests and Interviews aim at assessing candidates' knowledge in programming and problem-solving techniques. For Questions presented in these assessments, candidates are expected to provide their own original answers. Your test setters may use practices such as proctoring to keep a tab on malpractices by candidates.
For Coding assessments, in particular, HackerRank uses a powerful tool to detect plagiarism in the candidates' submitted code. The Test report of a candidate highlights any plagiarized portions in the submitted code and helps evaluators to verify the integrity of answers provided in the Test.
The plagiarism detector uses specialized methods to identify and report:
- Any overlaps in code submitted by different candidates.
- Replicated code from original sources on the internet.
- A code that is reproduced by changing the variable names, formats, etc.
- Any suspicious activity was observed during the test.
Therefore, it is recommended that you submit your original solutions in HackerRank's assessments.
