■ Official Question Revisions
If an official question contains outdated or inappropriate content, we first notify all customers and then release an updated version.
We adjust difficulty from two perspectives:
Absolute difficulty based on the test cases included
Relative difficulty based on aggregated answer data
For our difficulty standards, see Types of Track Test Questions.
■ Official Question Closures
In principle, we do not close questions that are already in use by customers.
However, if a question is deemed unsuitable for maintaining screening accuracy, we may retire it after consulting with affected customers.
If you notice any issues with our content, please contact Customer Success.
