I applied through an employee referral. I interviewed at Oracle
Interview
Talked with recruiter and immediately was invited on site. I was recommended by a friend who is an Oracle employee so maybe that got me past the screening process. Met with the team for mostly laid back interviews. There was a coding problem on a computer with an editor and the ability to look up details online while programming. Then they asked you about the time and space complexity of your solution. There was also a white board coding interview and a few behavioral questions ("Tell me about a time when...").
There was a second phase where I would have brought a coding sample to discuss and give a white board technical talk, but I decided not to come in for round 2.

Question 1
The questions were similar to those in Cracking the Coding Interview or one of the other popular books. Definitely worth studying if you are rusty on your undergraduate level algorithm design.
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.

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
