Interviewed with an Apple IS&T team for an SDE role. Got asked below questions in the phone screen:

1) How JVM works? How memory gets managed internally?
2) How Java Collections.sort works? What's the best case time complexity for it? (Best case is actually O(n) coz it uses timsort but I answered O(nlogn) assuming it uses quicksort😢)
3) How jdk 11 is different from jdk 10? 😵‍💫
4) Gave me two SQL queries and asked me which one would run faster.
5) Java immutables (Answered correctly)
5) Questions on OOD (Answered correctly)
6) Java annotations (Answered correctly)

Failed the phone screen.

I've been focusing on design and LC till now for interviews.

Is it expected of me to know the answers to questions 1, 2 & 3?
