Oracle

Simple data structure and algorithm questions about linked lists and graphs were asked. Concepts about operating systems, basic networking, and core Java questions were also asked. The interview process was pretty relaxed and felt comfortable.

Some medium LeetCode questions, technical questions about data structures and data efficiency, discussing the complexities and efficiencies of different approaches. It was quite long but regular stuff for a computer science background.

Cleared all technical rounds, only to be rejected by HR with nonsensical questions that would make you question your sanity. Luck plays a major role in who you get as your interviewer here.
