The process took 3 days. I interviewed at Oracle (New Delhi)
Interview
Hiring process took 3 days and 6 rounds of interview. ~1 hour each.
HR asked me to finish all 6 rounds in 2 days and scheduled virtual interview. The entire interview went well and the interviewers are very cool and focused. But, I was rejected at the end.
I have spent almost 6-7 hours for giving the interview, and then I was told that I was rejected. The HR, who responded well till then started rejecting the call and when I asked for feedback over email, she didn't even care to respond back(even after multiple follow-ups). I don't really understand why these people don't care about the candidates once they are rejected. Common, I have wasted my 6-7 hours of time for the interview and you don't even give feedback about what went wrong? If you are so busy, don't schedule interviews then. I have all the right to understand what went wrong and correct myself. This is not expected from a reputed company.
HR informed me that there is a BT(Behavioral test) round and it is non technical. But when I joined the interview, they started putting tech questions. When HR herself isn't clear of what round it is going to be, then God must help the candidates.

Question 1
Coding questions, situational questions and other tech questions
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.
