When I was doing interviews at my old job we did an hour of pair programming and we very intentionally designed the exercise such that

1) if you're qualified to do what we're hiring you for this stuff should be your bread and butter. We were doing restful web apps so the prompt might be "A restful API that takes in a string and returns that same string but backward." If you chase your tail on that for 15 minutes, you're not right for this job.

2) We weren't looking for a specific implementation. You want to make it a GET call with a query param that returns just the string? Neat. A POST with request and response DTOs? Also neat. We're not gonna ding you for doing it one way rather than the other but we're definitely gonna talk to you about why you made the choice that you did and maybe try to tease out another choice you could have made so that we can ask you to compare them. Again, the only wrong answer here is one you can't defend.

3) I'm not here to test your ability to memorize a particular language's syntax, your IDE's autocomplete or your ability to google. If you can articulate that you're trying to create a POST endpoint I'll give you that the correct annotation with Spring is @PostMapping or little things like that.
