𤯠You won't believe the Questions Oracle asked in their Oracle Cloud Engineer Interviews
Many dream of getting a job at Oracle as a Cloud Engineer, with a tempting package of 26 LPA (Lakh Per Annum). However, the competition is tough, and success depends on handling Oracle's challenging interview questions. Let's explore some of the most thought-provoking questions candidates have faced and how to prepare for them.

1. Scenario-Based Questions
Oracle wants to see how you think on your feet. Here are some real-life scenarios candidates faced:
Q."Youâre tasked with migrating an on-premises application to Oracle Cloud Infrastructure (OCI). How would you approach this migration while ensuring minimal downtime?
Purpose: Tests your knowledge of OCI services, migration strategies, and downtime mitigation techniques like live migration or rolling updates.
Additional Insight: Highlight tools like OCI Data Transfer Service, Zero data loss migration ZDM ,Oracle GoldenGate for data replication, and pre-migration testing.

Q. "An Exadata Cloud@Customer database is running out of storage. What are your options to address this issue?"
Purpose: Assesses your understanding of Exadataâs scalability features and resource management.
Key Points: Discuss options like adding more storage servers, optimizing database usage through compression, or archiving infrequently accessed data.

Q "A customerâs critical application is experiencing intermittent performance issues during peak hours. How would you investigate and resolve this?"
Key Points to Address: Use Oracle Cloudâs monitoring and logging services, analyze resource utilization, and identify bottlenecks.
Advanced Approach: Mention using Oracle Application Performance Monitoring (APM) or Database Performance Analyzer.

Q."Youâre tasked with designing a multi-region disaster recovery strategy for a global application on OCI. What steps would you take?"
Purpose: Evaluates your knowledge of high availability and disaster recovery concepts.
Bonus Tip: Highlight tools like OCI Object Storage replication policies, Oracle Data Guard, and Traffic Management Steering policies.

Q"A client wants to move their legacy database to Oracle Autonomous Database. What factors would you consider before making the migration, and how would you handle compatibility issues?"
Approach: Discuss data migration tools like Data Pump or GoldenGate, schema conversion, and pre-migration assessments.
Additional Considerations: Mention checking for unsupported features and planning for security configurations.

Q "A large-scale IoT system is generating terabytes of data daily. How would you design a data ingestion and storage pipeline in OCI?"
Purpose: Tests your ability to handle big data challenges.
Suggested Solution: Use OCI Streaming for real-time data ingestion, Oracle Autonomous Data Warehouse for storage, and Oracle Analytics for reporting.

2. Technical Deep Dives
Oracle expects candidates to know the technologies they'll work with. Some technical questions include:
Q."Explain how Oracle Cloudâs Autonomous Database optimizes query performance."
Key Points to Address: Features like machine learning-driven indexing and adaptive optimization.
Q."Whatâs the difference between Oracle Cloud Infrastructureâs Object Storage and Block Storage? In which scenarios would you use each?"
Purpose: Evaluates your understanding of storage solutions.

3. Problem-Solving and Debugging
Candidates often solve a problem or debug a hypothetical issue. Examples include:
Q."A virtual machine (VM) in Oracle Cloud is not accessible via SSH. Walk us through your troubleshooting steps."
Approach: Verify network security groups, check VM health, and analyze audit logs.
Q."A database query is running slower than expected on Exadata. What steps would you take to identify and resolve the bottleneck?"
Purpose: Gauges your expertise in database tuning.

4. Behavioral Questions
Oracle values cultural fit and teamwork. Behavioral questions reveal your thought processes and collaboration skills.
Q."Tell us about a time when you had to convince a team to adopt a new technology. How did you handle resistance?"
Q."Describe a challenging project where you had to balance competing priorities. What was the outcome?"

5. Whiteboard Exercises
Candidates may be asked to sketch solutions on a whiteboard. These exercises test your ability to articulate your thought process.
Q "Design a highly available architecture for an e-commerce platform using Oracle Cloud services."
Expectations: Include load balancers, multiple availability domains, and failover mechanisms.

6. Surprise Curveballs
Some candidates report unexpected questions testing creativity and adaptability, such as:
Q."How would you explain Oracle Cloud to a five-year-old?"
Purpose: Checks your ability to simplify complex concepts.
Q."If you were to build a cloud service from scratch, what would you prioritize and why?"
Purpose: Explores your understanding of cloud fundamentals.
