Sr. Recruiter interview as an Intermediate Recruiter

I am really thrilled to have gotten an interview for a Sr. Recruiting position with an amazing company. They initially wanted someone with 8+ years of experience and have considered my profile with a little over 2 given how aligned my background is.

I have performed many of the same responsibilites/functions as many other Sr. Recruiters but am not sure what unique experience-based questions may appear during the interview - do they actually care about KPI's? Do I need to be ready to explain my experience in "leveraging data insights to streamline recruiting processes" or is it just fluff for the most part? I've created a really dense sheet to prepare but thought it might be beneficial if any Sr. Recruiters here could give relevant input or a word of confidence as someone hungry and hoping to make this work.

Thanks
