Ho presentato la mia candidatura tramite segnalazione di un dipendente. Ho sostenuto un colloquio presso Oracle (Seattle, WA) nel mese di set 2020
Colloquio
The first technical interview was a 45 min long simple enough coding question just to gage the candidate's ability to code.
The second and final interview lasted about 5- 6 hours.
I was interviewed first by a senior engineer who asked mostly behavioral questions like "what would you do if your teammate / superior took all the credit for your work" or "tell me about a time you had a disagreement"
Second person asked me a really difficult coding question, he was very difficult to understand (accent was very thick) I did not do well at all, there was a misunderstanding on my part on what was the expectation.
Third person was a senior engineer and he asked a simple leet code question and followed up with a qeustion on how to make my solution more efficient / adding more complexities.
Fourth person was another SDE engineer on the team, he asked me about sorting algorithms and a few simple followup questions.
Fifth person was another senior, he asked me a question about trees and followed up with asking for different methods of traversal (BFT and DFT)
Overall the questions were easy-med (leetcode level) but unfortunately I didnt seem to impress them.

Domanda 1
Tree traversal questions, Bubblesort, Leetcode mediums and easy (with follow ups)
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.

Domanda 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.

Colloquio
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
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.
