I did really well in all rounds except for system design; In SD I mentioned some tech that I didn't know too much about, but I know what they do and interviewer asked me for internals details.

Advice:

1. Prepare really well for system design interviews.
2. DON'T mention a tech you don't know much about, if you want to, make sure you not just understand what problem it solves, but a little bit of how it solves.
3. Think out loud of base cases and ask clarifying questions.
4. I felt some problems are intentionally vague, so ask questions even if it's a little obvious.

Verdict: Ghosted/Rejected.

All the best!
