I applied through an employee referral. I interviewed at Oracle
Interview
Talked with recruiter and immediately was invited on site. I was recommended by a friend who is an Oracle employee so maybe that got me past the screening process. Met with the team for mostly laid back interviews. There was a coding problem on a computer with an editor and the ability to look up details online while programming. Then they asked you about the time and space complexity of your solution. There was also a white board coding interview and a few behavioral questions ("Tell me about a time when...").
There was a second phase where I would have brought a coding sample to discuss and give a white board technical talk, but I decided not to come in for round 2.
Interview questions [1]
Question 1
The questions were similar to those in Cracking the Coding Interview or one of the other popular books. Definitely worth studying if you are rusty on your undergraduate level algorithm design.
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
