Automated tests run in parallel in eight processes against a single test environment and keep conflicting over identical emails and logins. Write a test user factory: it returns a valid user with unique fields, lets you override any field, and can create the user through the API with automatic cleanup after the test.

How to approach it

They're checking whether you understand how test data isolation works under parallel execution. You need a factory that generates unique values without shared state, doesn't mutate the defaults, separates building data from creating it through the API, and reliably cleans up after itself even when a test fails.
