This is different. The engineering team provided those questions so that the recruiters stop wasting their time on people who have no chance at all. They're just implementing the filter. HR themselves did not come up with any of them, and don't make the decisions. Also, recruiting and HR are not quite the same function.

I talked to a person in a similar situation... ironically some of the questions could have multiple answers. Pre ES5 and Post ES5 JS has changed a lot of the "rules". Specifically to scope/closures.

But yeah, for the most part, those kinds of questions help. It does depend on what your needs are.

I’ve been screened by a Facebook recruiter without that experience. Sounds absolutely dreadful.

I had a very similar experience with LinkedIn a couple years ago.
