I applied through a recruiter. The process took 3 weeks. I interviewed at Oracle (Hyderābād) in Jun 2019
Interview
I got the call from its Talent Acquisition team & those people were not looking much interested, as were not much eager to interact & listen. People share a long list technical stack & expect the person to answer their question on any of those items.
First round was on general technical questions & I didn't get the feedback on that but got the problem for coding exercise. So I submitted the code for the problem given. Then I was called for the discussion on the code submitted 10 days before & I was not told to carry my laptop. Anyhow they provided me the laptop & asked me to make some changes in the code there in front of them. For me that gap of 10 days was not good & I was not able to make the changes there. Though some people told me not to join Oracle but still I tried. And I will not say good or bad about Oracle but I was not happy with the lazy interview process I observed there & even these people don't show courtesy to give the feedback after the interview.
Interview questions [1]
Question 1
Interview questions were around stacks, queues & collections.
Coding exercise was to code for the family tree.
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.

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
