I applied in-person. I interviewed at Oracle in Apr 2017
Interview
This review is about the Oracle Bare Metal Group. Interviewer was very rude with unprofessional behavior over phone. I was asked one question on graphs for the initial phone screen. Interviewer stopped me in the middle and behaved very rudely because i was taking time to analyze my logic.
Interviewer bragged about top engineers from facebook, google etc in his team and if he hires me then i will end up struggling. I was rejected over phone itself.
I don't recommend people to interview with bare metal group because of their unprofessional attitude.
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.
