Weird. For a specialized job, I was tested using front-end software engineering questions. I would equate this to testing a UX/UI Researcher using back-end engineering questions. Because they were "interviewing blind," meaning not interviewing for a specific job but for fit, I was never asked any questions relevant to my experience or the positions I applied for. "Interviewing blind" works fine when looking for a culture fit. However, if you are live coding to assess skills, then you should review the candidate's resume/LinkedIn and ask relevant questions.

Build logic to adjust various input strings to a more generic output string.
