The OA test was incredibly hard. I don't think they're looking to hire any real life developers to build real world business applications.
They want to hire pro leetcoders or competitive programmers. I think they are planning to compete in world programming championships. Good luck!
They are kidding themselves if they think they are like Big Tech.
See the question. OA and leetcode is ruining this process and industry. Let's game it.
