I applied through college or university. The process took 1 week. I interviewed at Oracle (Bengaluru) in Aug 2022
Interview
1. Technical Interview - Easy, Med DSA questions in Java [Time: 1hr]
2. Versant Test - English Verbal & speaking test to analyze the candidate's efficiency.
The mode was campus placement.
Interview questions [1]
Question 1
1. Find the missing element in the array with O(n) complexity.
2. Algo to find the transpose of a matrix.
1 technical phone screen covering basic networking and data structures, followed by a 4-round onsite loop focused heavily on Oracle Cloud Infrastructure (OCI) scale challenges. The rounds were split between low-level system execution, multi-tenant cloud architecture, and standard relational/non-relational database trade-offs. The interviewers kept drilling into network virtualization, hypervisors, and storage layers.
To prep, I needed to brush up on high-throughput cloud networking patterns and storage engine internals. I utilized Apex Interviewer to simulate full cloud infrastructure design problems.
Interview questions [1]
Question 1
Design a highly secure, multi-tenant virtual cloud network block storage migration system that allows live volume transfers between physical data centers without dropping active I/O operations.
Mostly coding question focused, and some talking about personal experience and terms. Some technical design, you could have chosen any language to complete the coding questions. Questions were simple technical concepts that person came up with at the moment.

decent amount of DSA and System design were asked, and behavioral questions. so prepare leetcode level questions and good amount knowledge in sql, java and also mostly oracle sql. overall it was good
