I applied through college or university. The process took 3 weeks. I interviewed at Oracle (Ciudad de Mexico) in Mar 2017
Interview
The screening interview was done in the offices at Mexico city. The person that made the interview asked me about my master's degree thesis, and about the courses that I took during my graduate studies. Also he told me about the project he did.
The second interview was made with a webcam and with a phone conference. There was a manager from the U.S. and two people from the team where I would work in case of getting an offer. The first part was about a coding problem (1 hour) and the second part was about a machine learning problem (1 hour).
Interview questions [1]
Question 1
You have a rectangular keyboard with letters A to Z, ordered sequentially from left to right and up to down, but the number of columns is given by number N. Given N and a string S, print the actions that you have to make in order to type the string S. The available actions are U (up),D (down),L (left),R(right) and Enter.
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.
