Oracle Software Engineer interview: LRU cache and course ordering

The technical rounds were more demanding than I expected. The questions did not seem unfair, but the interviewer energy and live problem-solving pace kept me switching gears. I implemented an LRU cache and then worked on a course-prerequisite ordering problem, which made me think about ordering constraints as well as code.

The final round was the most stressful. I had to maximize the area trapped between vertical lines, and getting the reasoning right under time pressure felt more intense than the earlier tasks.

The process was challenging but engaging, with a constant need to keep moving. I accepted the offer. My takeaway was that it rewarded clear reasoning more than knowing a particular trick.

Location: United States. Overall feedback: positive. Offer status: got offer.
