The first round in the recruitment process of Oracle was the written test. It was an online written test. The test consisted of 6 sections: logical reasoning, aptitude, programming, English and a 5 minute quick test. I cannot recall the 6th section. In 5 minute quick test section the questions were like finding the incorrect number in the given sequence of numbers or finding the next number in the given sequence of numbers and so on. In programming section the questions were from data structure and database management. However, not a lot of weightage was given to this section, even a candidate who had performed well in the other sections but not so well in the programming section qualified for the next round.
Oracle shortlisted 40 students for the interview round.
Interview:
Round 1: Personal Interview
In the interview I was asked some programming questions and some puzzles.
Some of the programming questions were:
What is binary search? Write down the code for the binary search for finding a number given a series of numbers.
Finding the power of a number. For example 2^3

Question 1
If there are 8 coins out of which 7 are of the same weight and the remaining one with slightly different weight then how to determine the odd coin in three ‘weightings’ using spring balance. All the coins are of the same dimension
There are 100 steps and an ice cube. There is a particular step and all the steps above it from where if the ice cube is thrown then the ice cube would break. What is the minimum number of tries required to determine that step.
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.
