Good suggestion. The latter is certainly what I'm hoping for, in the latest case the company did have a more general skill-set requirement, and I proceeded through the first two rounds without issue. They then issued me a test limited to 8 hours in React (which I really had no issue with technically), which I hesitantly started hoping to get it done quickly. It took me longer than I thought, simply because I wasn't expecting it to be in React and it had some finicky bits, but not terribly long. I ended up ending it at around 5/5 test cases on the first and 3/5 on the second due to time constraints. That was a week ago, they rejected me this morning after I prompted them. I get the sense nobody actually looked at it, or they had such a large funnel that they were able to pick some specific thing they didn't like.
