Apple internship advice - very scared

Hello guys, I have interviews coming up with apple SEG PMU and RF HW team. I have master's degree but never did any sort of internship. It's a 50 minutes interview and the first one (recruiter reached out by email). It would be less to say I'm terrified, I'm very frustrated realizing my inexperience in internship interviews. I have no idea how these interviews go, let alone apple interviews. Can you guys please help anyway with educating me about these internships at apple? Do they start with behavioral questions or current research or ask to explain your projects? And how do they ask technical questions for EE since there's not a lot of coding problems to solve? How can I prepare myself? I'm so nervous that I think I'll embarrass myself at the interview.

Any question banks for apple interviews?
