Anyone here interviewed for the platform team in Apple Siri or SDE (non-ML role) for Apple Siri?

I was approached by an Engineering Manger from the platform team in Apple Siri recently based on my experience with C++17 and networked systems on past co-ops. We talked about my work , my next co-op (again C++ and storage systems based), and the work his team does (mostly networked systems stuff for Siri in C++, Golang). He told me about the next steps i.e 2 phone screens + onsites. I told him I need five weeks to prep as I haven't done any Leetcode prep since 6 weeks. He agreed and my phone screens have been scheduled for the 1st week of March. Anyone interviewed for this team before or for an SDE role with Siri? What kind of questions do they mostly ask (LC medium , hard?) ? Thanks. TC - None, still in grad school.
