At my last job, I set up something like this. We were specifically interviewing people who claimed to have frontend and Angular experience - I confirmed this on every resume before the interview and again with the candidate before explaining the test. To test it, I gave the test to 2 coworkers who each completed it in under 15 minutes. Candidates were given an hour for it.

The test was a JSFiddle pre-filled out with Angular boilerplate. It had comments in places where things needed to be added and filled out. Just to be clear, there was no gotchas or tricks involved. It was very simple: "get JSON from this public HTTP endpoint, display it on the page in a table and then add a filter field. If there's time, add some CSS to make it look pretty."

Candidates were encouraged to use docs and Google if they couldn't remember off the top of their head how to do those. More than one candidate copy/pasted from Stack Overflow during the interview and while I wasn't impressed, I didn't count it against them.

Several candidates completely failed at it and I suspect it was a combination of nerves and lack of experience (one candidate it became clear that he had never used Angular before and he never got past the "get JSON from an HTTP endpoint"). During the test, I was more than willing to talk through the code with them and help them figure out the best way to do it. The one candidate who passed it was hired and they were very successful at the company.
