Oracle Interview Experience

Position: Application Developer

Coding Round:

The online assessment contained a few aptitude questions, two easy DSA questions, and one REST-API related question on a coding platform.

Technical Interview:

Round 1

I introduced myself to the interviewer, a normal introduction. The interviewer asked me which recent web-series I had watched. I talked about a HBO documentary on the nuclear plant disaster in Chernobyl.

There were questions on:

• Inheritance (based on the diamond problem)
• Inheriting base classes in private, protected, and public mode
• One puzzle similar to the Camel and Banana Puzzle
• Why doesn't Java support Multiple inheritance and stuff

I asked the interviewer how Oracle handles synchronization between distributed databases. He liked my question and explained the system behind maintaining such a sophisticated cloud platform provider.

Round 2

This round was long and one of my favorite rounds. The interviewer was cool and asked for my intro. He asked some questions regarding my projects, including:

• What shall you do if your webpage doesn't load properly?

There were some technical questions as well, like:

• Regarding REST APIs
• Some IP protocols
• OSI Model
• Utility of Transport Layer
• The requirement of Normalisation
• Explain the types of joins
• Some questions related to Virtual Memory
• SDLC

I couldn't answer the last question. But I soon realized why he asked that, because his team worked with DevSecOps, which required continuous development, deployment, and monitoring cycles while not keeping security in the hindsight.

At the end of this round, I asked the interviewer what I could expect to be working on in the initial days as a fresher, since Oracle deals with several latest innovations like IoT, ML, and AI. He liked my question and answered that they would assign me to the DevSecOps team if I were selected.

Round 3

This round was taken by the Vice President of Oracle. He asked for my general introduction and was very sensible and nice.

He asked me the famous Monty Hall problem. I explained a general DFS approach to find a loop in a tree.

He also asked me for the pseudo code for DFS and BFS. He questioned why normalization is needed and why there is sometimes a need for denormalization as well.

So that was it...

My interview was finished at around 3 pm, but my rejection news came around 8:30 pm.

My take from the interview: Please don't neglect the HR questions. They too can become a core decider in your selection probability, even though the technical interview itself was no brainer.

Final verdict: Rejected
