I applied through a recruiter. The process took 1 day. I interviewed at Oracle in Feb 2018
Interview
Firstly the HR will contact you with the information to book the travel. The flight and hotel expenses just went through the company's bill. You can also book the car rental, and have a look at San Francisco before the day of the interview. The reimbursement policy is pretty generous.
I interviewed with three teams. Most of the interviewer are team manager. The first team asked a lot about the projects on my resume, as well as some knowledge might be used in their group. And they also ask something about basic language usage. The second and third group asked some algorithms questions, they are just common questions which you can find in leetcode.
Interview questions [1]
Question 1
Do you know something about java GUI, java multi-thread?
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.

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.
