> At least the reason why we have Leetcode questions is because Google did the research and came to the conclusion that those are were good at algorithms ended up being more successful at Google, That's just part of the process, though. They (and many others) have coding questions, system design questions, and behavioral questions. Taken together, they answer the questions of whether you can write code, design/build/contribute to a coherent larger system, and are someone who can be effective at working with others in a company. Over time, there's been a massive (IMHO) over-index on the coding portion, since it can usually result in an objectively correct or incorrect answer. With massive numbers of applicants, companies really don't lose out on being over-aggressive with cutting people based on these things. As they tighten their hiring belts, I think this will get worse.
