I applied online. The process took 3 weeks. I interviewed at Oracle (Chennai) in May 2019
Interview
Applied through Naukri.
Got a call from HR asking if I am available to attend interview in Chennai office on Saturday for Bangalore location.
I happily agreed and got the interview call letter.
Went to Oracle India Chennai office. There were around 6 candidates who went to the wrong interview location in Third floor for PLSql developer. Then we we're about to leave as we didn't know what to and where to go. Then we all asked the security where the interview is happening. They told Forth Floor.
When we went there, we saw around 30-40 candidates attending the interview . There were 6 panelists to conduct the interview.
I gave my resume to the POC mentioned in the interview call letter and waiting for my turn to come.
Finally after 40 mins my turn came for First round. There were supposed to be total three rounds to be conducted.
First Round started. He was very friendly . He told his name and asked me to introduce myself. Then he gave me one Program to write and went to attend other candidates and have lunch. The program he gave was to return 120 out of 5 Zeros. I was not able to think logic for very long time. Then he came and gave me hint saying Factorial. Based on that I wrote the program.
Then it became too late so he asked me to go for lunch.
Once I came back from lunch , he asked me some basic questions from Core Java. I answered many of them confidently.
Then they said me to wait does second round. I waited for some 2 hours for my turn to come as there were many candidates and for each candidate they took around 40 mins Interview.
In second round the person was very friendly. He asked me to write two programs plus questions from my resume. I had mentioned powermockito so he was asking that only.
After again 1 hour wait went with Third round.
Third round again they asked me to write a program , I was not able to concentrate or solve as I was very tired. It was already 6 p.m , so the Manager asked a Puzzle. Until I could think to solve they told me they will conduct Telephonic round as third round.
On Monday the Telephonic round went for around 1 hour. It was all scenario based questions
If we have a Cat class and we create two objects of Cat class . What will happen if I try to add it in a Hash Set collection. Will it add or throw exception. How to avoid duplicate object addition in such case.
If we have 10 bags with 10 coins in 9 bags and 11 coins in 1 bag. Each coin weigh 1 gram. By using only one Weighing scale and measuring only once vhow will u find out which Bag had the 11 coins.
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.
