The way I handled interviews during my short stint as a manager was to just ask questions related to the task the person was going to do. No general "coding questions", no need for that, the specific topic they'll be working on.
"Have you heard of X? How would you deal with Y in situation Z? Your CV says you worked on A, have you also looked into B? Any guess why we went with B instead of A for C?"
They didn't need to give the exact answer we wanted, the questions they asked in response often told us more than the straight answers.
Everyone I hired is still at the company and one of them sped up our tool by an order of magnitude. No coding challenges needed.
