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.

Question 1
Do you know something about java GUI, java multi-thread?
Se divide en varias etapas, lo primero evalúan tu ingles, ya que es requisito para trabajar ahí, normalmente es solo una entrevista en ingles con preguntas sencillas, como cuál es tu actual trabajo, por qué quieres trabajar en Oracle, y normalmente es alguien de RH, después si pasas esa etapa viene la entrevista técnica en la que te preguntarán conceptos básicos, por ejemplo si es para java te preguntarán sobre herencia, polimorfismo, era entrevista puede ser en español o en ingles dependiendo si es alguien de aquí de México tu manager o si es del extranjero y posteriormente te pondrán problemas de algoritmos que tendrás que programar en el tiempo de la entrevista
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.
