> I'm unclear what employers are deriving from this exercise at this point
It filters out the complete frauds.
Yes, there are people who know all the right things to say in a job interview, but cannot code at all. If you hire one of them, it takes a bit to find out they cannot code, and a bit longer to fire them, so you're out $$$$ paying their salaries for nothing.
For example, a recruiter I know will ask a tech candidate "what is 20% of 20,000?" A significant percentage cannot answer the question. Some even cry. It's shocking.
A friend of mine was looking at getting a FAANG job. He was worried about the leetcode tests. I suggested he spend a month going through the leetcode books studying them - that the return on his time investment doing that will be one of the best ROIs he's ever done. He did, and got the job. (Although the LC was just a first gate one had to go through to get to the real job interview.)
Personally, I have no idea how I'd do on an LC test without prep. But I don't have a problem with studying it to get a top job.
