Any advice for good Stats Interview Prep?

Statistics

Currently in the job market as an experienced Data Scientist generally targeting Senior/Staff roles that span Data Scientist/Applied Science/MLE. I have an MS in Stats, so one thing I've generally focused on during my interviews prep is overindexing on coding and ML specifically leetcode. This has me taking the Stats portion of interviews for granted and it's causing a blindspot for interviews I would consider "not as crisp" as I'd like them to be.

What I find is generally I know the conceptual definition of a lot of things and a lot of breadth and how to connect that back to the business, but will have random gaffs on things I've forgotten or being able to go one layer deeper on the spot. Don't use on the job or haven't used in depth since Grad school. Things that aren't hard but my mind just goes blank for some reason in an interview setting. Common examples can be things such as forgetting the name of probability distributions, confidence interval calculations for proportions, formula's for power analysis as opposed just know the inputs, etc. Sometimes it's also tricky just to understand WHAT an interviewer is driving towards and not going off on a tangent in a complete opposite direction.

I use LLM's extensively but I find that sometimes if the convo goes on too long they get "stuck" kinda repeating the same questions and same themes instead of exploring other stuff.

Curious how you all prepare for Statistics interviews and if there are good resources for full coverage to prevent some of what I talked about?
