Entrevista
I interviewed in Oracle OCI at Pleasanton office. They scheduled my phone screen interview twice and they interviewer did not show up twice. I was called for onsite interview directly afterwards. Out of all the onsite interviews, 2 interviewers (one of them was hiring manager) were very rude and arrogant. There was one lunch interview with the hiring manager and the hiring manager finished the lunch quickly without talking much and waited for me in the interview room for a quick whiteboard question. He gave me 15 mins to solve it and I obviously could not solve it in 15 mins. So, they called it "lunch interview" but they tricked me into doing whiteboard coding in last 15 mins. This approach was very shady. I have interviewed at big companies before and this is the first time I have done whiteboard coding in the "lunch interview". One interviewer had no idea about how docker works and why people use docker. He kept asking me about docker and exhausted more than half of the time and then asked me a whiteboard coding question. Cultural fit interviewer was decent and knew what he was asking. The hiring manager told me that he will let me know personally within 2-3 days. I never received any email communication from the hiring manager after that. I was told by many people that OCI is not doing well and the culture is toxic. I should have listened to those people instead of wasting my time interviewing for them. I do not recommend interviewing for OCI Pleasanton office 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.

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.
