The interview process at Oracle consisted of four stages: an online assessment, two technical interviews, and 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 2 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”, “Where do you see yourself in 5 years?” were asked. STAR method helped me structure my responses.
Preparation Strategy:
I focused on practicing DSA for at least 2 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.
