Microsoft Senior Developer interview questions

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. Got sent reems of prep material that was either impossible to do (know details about the role, and the people interviewing me), or was review stuff that wasn't matched up with what I asked (e.g. design Netflix/YouTube, design an Elevator System). Much of the information I got ahead of time conflicted with each other. I spent 5 hours (including breaks) on interviews. I thought I did reasonably well, but apparently not good enough to move on. I thoughtI had a good rapore with everyone. In the end, the interview coordinator told me I didn't do well enough, but invited me to apply again in the future. When I ask when I can apply again, and for details on what I did well / what I didn't do well, I get 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.
