Interview prep for 10+ year experience

I recently interviewed but I am an IC even after 10 years (and plan to remain such). I do have lead responsibility but delivery is managed by Program managers at every place I interviewed as well as the current place. (All public listed orgs).

There is generally a programming round to assess technical expertise. There is focus on low level design. There can also be code review sessions where you are asked to understand a snippet and identify bugs.

One org had a program manager as part of the panel and they asked about challenges I face as a leader - we discussed priority vs schedule and assessing capability of the engineer assigned a task.
