Applying at Anthropic was a bad experience for me. I was invited to do a timed set of leetcode exercises on some website. I didn't feel like doing that, and focused on my other applications.

Then they emailed me a month later after my "invitation" expired. It looked like it was written by a human: "Hey, we're really interested in your profile, here's a new invite link, please complete this automated pre-screen thingie".

So I swallowed my pride and went through with that humiliating exercise. Ended up spending two hours doing algorithmic leetcode problems. This was for a product security position. Maybe we could have talked about vulnerabilities that I have found instead.

I was too slow to solve them and received some canned response.
