Passed the online assessment, which consisted of two easy or possibly medium-level LeetCode questions.

Coordinated setting up an interview through various recruiter contractors who refused to speak with me about the role. I was sent reams of prep material that was either impossible to complete (know details about the role and the people interviewing me) or was review material that didn't match what I asked for (e.g., design Netflix/YouTube, design an elevator system). Much of the information I received ahead of time conflicted with itself.

I spent 5 hours (including breaks) on interviews. I thought I did reasonably well, but apparently not well enough to move on. I thought I had a good rapport with everyone. In the end, the interview coordinator told me I didn't perform well enough but invited me to apply again in the future. When I asked when I could apply again and for details on what I did well and what I didn't do well, I was ghosted.

I've interviewed at dozens of places, and this was by far the worst set of recruiters I've ever worked with. They should be ashamed.
