Micron Technology Site Reliability Engineer interview questions

From India team there were 2 interviewers. They started with the introduction about themselves and the asked about me. Why I want to be a SRE? Then the technical round started. Started with some basic questions related to C++ and then followed by medium level questions related to DSA and algorithms. Then at last had few questions related to SQL. Then a week later had the interview with the Boise team. There were 5 interviewers. With them it was more like a discussion rather than an interview. started with introduction then a output deriving question from C++. Then one by one they started asking about by experience, about all the other projects which I had done in my internships. They asked about what tools were used, how did the ci/cd pipeline designed. They focused on the entire flow from writing a code, testing it. Merging it and then deploying it. Then they asked about my experience with docker, kubernetes, openshift, foreman, ansible. Which I had none. This interview went for approx 1.5 hrs. We also had a very detailed discussion on our project. Why was it required? Was there any other way arround.
