Oracle Software Developer interview questions

I recently went through a 3-round interview process. The first round focused on LeetCode hard-level problems, and also tested computer systems knowledge, including OS, networking, and Linux internals. The second round involved a file processing task, where I had to write efficient code to handle and transform structured data. The third round was a behavioral interview, centered around past projects, communication skills, and how I handle challenges. Across all rounds, strong preparation in computer science fundamentals—data structures, algorithms, and systems—was essential.
