I applied through an employee referral. The process took 2 weeks. I interviewed at Oracle (Menlo Park, CA) in Oct 2010
Interview
One hour phone interview, asked some questions about the projects that I worked on. And then asked some algorithm questions, the questions is very simply. One week later, get an on-site interview. the interview has 3 rounds:
The first round: Questions related to OS, Kernel etc.
The second round: Questions about the projects I have worked on, like which one is your favorite and why, describe the technical details.
The finial round: Questions about data structures and algorithms. Sort a linked list, improve the performance by multi-thread (suppose on a multi-core system).
Interview questions [2]
Question 1
Questions about OS and kernel. How an IO request processed by system, from user mode to kernel mode.
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.
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
