I applied through college or university. I interviewed at Oracle (Vellore) in Aug 2016
Interview
There were many rounds and each round was elimination round except the coding round. First was a online test which consisted of many sections and time was limited for each section. It was tough given to time constraint. Next was a online coding round where 2 question were to be done in 1 hour. Then there was a paper pen round where mainly puzzles were asked and 1 coding question was asked. They asked puzzles mainly in the interview process too. There were 2 technical and 1 HR interview.
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.
Interview questions [1]
Question 1
Something like searching in logs using maps and filter/find data
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
