Data structures and algorithms are used in interviews, not because you'll be expected to implement sorts and linked lists, but because they demonstrate that the candidate can implement and troubleshoot software from specs, using cases they should be familiar with if they have a CS / coding background. Testing for skills rather than knowledge. By the same token, it makes sense to test candidates on the use of AI assistants, if they'll be using those in their work. Though rather than let them produce textbook algorithms with prompts, I'd give them a prompt that produces known faulty output, then ask them to test the result, figure out what is wrong with it, and fix the code and/or the prompt.
