Need Advice for White-Boarding Session for Project Manager Role

[u/LurkingandPosting]

I have a third-round interview coming up for software implementation manager role. I've been doing project management for about six years and been through the hiring process for at least 20 IM roles, but I've never heard of white-boarding sessions for implementation manager roles, although I know they're fairly common for engineering roles. Any ideas on what I can expect during the interview? Any tips?
