Oracle Sr Software Engineer interview questions

We had interview with human resource manager followed by 2 technical interviews and with hiring manager at the end. Human resource manager asks you desired salary and gives you introduction to selection process. Technical interview can include general technical and technology questions (HackerRank may be too) and system design and technical questions about Java technology.

Recruiter reached out with generic questions, compensation and then emailed a link to schedule the phone screen. Technical Screen: Interviewer was very friendly. It was a discussion about my past experience and some behavioral questions. Then asked me a leetcode medium question. Solved it, I was moved to next rounds that are called loop interviews. There will be a 30min session with HR to understand what can be expected in the loop rounds. There will be 4 rounds on the same day with 2 coding challenge rounds, 1 system design and 1 Behavioral with hiring manager. Round 1: Coding challenge the interviewer was interactive. Asked a leetcode medium on graphs and some behavioral questions. Round 2: Behavioral with HM. This interviewer was not friendly at all. I have never interacted with someone who can drain all my energy. It seemed like no matter what I say, he had a very judgy look and was not welcoming. I usually do well in behavioral interviews but this was a disaster. I lost all my hope after this round. But pulled my self back for the next rounds soon. Round 3: System Design. It was a great conversation and I did well. Very warm and friendly interviewer. Round 4: Coding Challenge. Was asked a leetcode medium on graph shortest path from source to destination. The recruiter was very friendly. Verdict: no hire
