I applied online. The process took 2 days. I interviewed at Oracle (Prague) in Feb 2021
Interview
First round is a general cultural fit kind of interview. The second interview is technical tests and whiteboard questions. The manager I had a meeting with was friendly and warm.
A different topic, their interview process is just like any other interview process in the industry where they try to decide if you're good enough fit within only 2 hours and they will skip you if you failed to show them that you're the amazing dev they're looking for within those 2 hours even though they will be most of the time giving you the questions; it's a common problem I found with other big companies that they will decline you for lacking a skill they didn't properly assess if you posses it or not.
A small tip for people applying to this company. If you check their list of employees, you will figure out that the majority of their employees are locals so if you're a foreigner to them, better apply to another organization.
I would personally give every company that doesn't assess my skills properly a negative feedback (or companies that suggest they're juniors but then answer they look for more senior) but I left it neutral here since their HR manager was nice enough to ask the interviewers for the feedback or the reason they declined my application and she did a great job following up on that and I hope that all employers in our industry will begin having this positive attitude and spirit to respect their candidates' time and feelings to at least give some sort of a feedback. This would also help to eliminate the imposter syndrome issue they cause to their candidates.

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.
