I applied through a recruiter. I interviewed at Oracle (Nueva Delhi) in Dec 2022
Interview
Round 1 - The Interviewer was polite and asked relevant questions Round 2 - The interviewer was rude and was not communicating, she was getting frequent calls and when I was clarifying the question, she was getting furious on that... The way of talking was not professional at all.

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.
