Senior level DS at FAANG - what coding interviews to expect

Worked at FAANG up until a month ago as mid level DS and now I'm getting callbacks for senior level roles from similar companies. My stats intuition/case studies are pretty good since that's mostly what my last job relied on. However, my coding is so rusty since I just used AI most of the time to move fast and cleaned it up when there was a mistake.

I'm mostly concerned about prepping the coding and data manipulation rounds. What level of prep should I prepare for to feel 'good enough'? Should I be expected to do leetcode mediums or is pandas/sql enough? Is describing the solution and logic with pseudocode enough for tougher problems or do I have to take it from start to end with no help? What has your experience been like for expectations at senior level FAANG interviews?
