Uber sse.

I have a sse interview with uber on Friday. I am done with 2 dsa rounds. Now it's about LLD in 1hr .I have read in many places that they need the entire code in 1hr.

Can someone help me with what they expect and what should we consider to code in 1hr. Design pattern/solid/oops /multi threading etc

Also if anyone has recently appeared please let me know some questions that they asked.
