Your materials were absolutely read (and indeed, RFD 576 makes clear that LLMs are not a substitute for reading materials). If you have writing samples that were external links, I can't guarantee that they were clicked through though: in part because the materials themselves constitute a galactic writing sample, we may have not clicked through because we were already at a decision point before reading your external writing. As for more specific feedback, if you can DM me, I'll see if I can give you more specific feedback -- but as we explicitly indicate in RFD 3[0], we are very limited in what we can provide.
As for your application getting flagged as LLM-generated: we in fact don't flag such applications (we just reject them), and it's very unlikely that we felt that yours were LLM-generated. (We really, really give applicants the benefit of the doubt on that.)
All of that said: absolutely no one is a shoe-in at Oxide. If you genuinely thought that (and if your materials reflected that kind of overconfidence), it may have well guided our decision. We are very selective in terms of hiring -- and we are very oversubscribed. Bluntly: it's very hard to get a job at Oxide. I know this seems harsh and/or unjust or unfair, but this is the reality. As we told you in the letter we sent you, we already have people at Oxide who prevailed on subsequent applications, because they found a job that's a better fit for them, or they have vastly improved materials (or both). Finally, you can also take solace in knowing that your post here in no way hurts your future chances at Oxide, and we look forward to reading your materials should you choose to apply in the future.
