The interview process at Oracle consisted of four stages:

• An online assessment
• Two technical interviews
• An HR round

Online Assessment: The first round was an aptitude and coding test hosted on HackerRank. It included sections on quantitative aptitude, logical reasoning, and two coding questions involving arrays and strings. Time management was key here, and I practiced using platforms like LeetCode and GeeksforGeeks.

Technical Interview - Round 1: This round focused on data structures and algorithms, with questions on trees, hash maps, and a few problem-solving scenarios. The interviewer also asked me to write code for reversing a linked list and explain its time complexity.

Technical Interview - Round 2: This round was more in-depth and included OOPs concepts, DBMS, and SQL queries. I was also asked to explain a project from my resume in detail, focusing on my role and technologies used. The interviewer appreciated clear communication and practical understanding.

HR Interview: The final round was mostly behavioral. Questions like “Why Oracle?”, “Tell me about a challenge you overcame,” and “Where do you see yourself in 5 years?” were asked. The STAR method helped me structure my responses.

Preparation Strategy: I focused on practicing DSA for at least two months and revised core CS subjects like OS, DBMS, and OOPs. I also followed Oracle interview experiences on sites like Glassdoor and GeeksforGeeks.

Challenges & Learning: The biggest challenge was handling pressure during the coding round. Consistent practice and mock interviews helped me stay calm. I learned that apart from technical skills, clarity in communication and confidence also play a big role in interview success.
