This was an interview with the hiring manager. Despite a fairly exciting description of the role, and despite hearing from multiple sources that a technical program manager title at Apple might have substantial agency and the ability to participate in the scientific community, it rapidly became clear that the role was more for a mid-level project manager and the questions I was asked were fairly basic project management questions. I didn't proceed to further interviews or an offer as it was clear on both sides that the role wasn't what I was looking for.
