This happened to me in am interview. It was my first software engineering job, so I was a junior. Wound up solving a problem one of the senior engineers had been struggling with for days. It’s probably what got me the job. Assuming the company is actually hiring for the role I think it’s perfectly fine to do this. It identifies people who can fill in gaps.
