Interview Process Practice - Reps and Actual Tasks

Hey guys, in these threads when you say practice your story and go through interview questions (basic behavioral answers, some quick math questions, other interview questions about your story/experience) what does that look like in terms of actual work?

I have some experience, but it's slow so the deals I will be talking about are months ago. For that I'll go over high level, what we wanted to do, what returns looked like, why we passed. For questions I was going to write out my responses then practice then 20x each to have a solid outline to go off of.

But curious what does your interview prep look like in actual time and reps (ie worked on this 5x for 10 mins, went to y). I know you don't want to have practiced answers, but you also don't want to come in cold either curious what others at the junior level do if work is slow so you need to practice reps you maybe expected to get at work.
