What does Oracle ask in an interview?

In an Oracle interview, the questions typically focus on a mix of technical, behavioral, and Oracle-specific topics, depending on the role you're applying for. Here’s a breakdown of what Oracle might ask during different interview stages:

1. Technical Questions

For technical roles such as software engineering, database administration, or cloud infrastructure, Oracle will ask questions that evaluate your coding, problem-solving, and system design abilities. These may include:

• Data Structures & Algorithms: Questions involving arrays, linked lists, trees, graphs, sorting, and searching algorithms.
  • Example: "Write an algorithm to reverse a linked list."
• SQL and Database Management: For database-related roles, questions focus on SQL queries, database design, and optimization.
  • Example: "Write a SQL query to find the second-highest salary in a database table."
• System Design: For more senior positions, system design questions may involve designing scalable and distributed systems.
  • Example: "Design a distributed cache system."

2. Behavioral Questions

Oracle uses behavioral interviews to assess how well you align with their values and work environment. These questions are often framed to explore your past experiences using the STAR method (Situation, Task, Action, Result).

• Example questions:
  • "Tell me about a time when you had to meet a tight deadline under pressure."
  • "Describe a situation where you worked in a team to achieve a difficult goal."

Oracle emphasizes values such as innovation, collaboration, and customer focus, so expect questions designed to evaluate how you’ve handled conflict, led teams, or contributed to project success.

3. Oracle-Specific Questions

Since Oracle is a leader in databases, cloud infrastructure, and enterprise software, they may also ask questions about their products or services, especially if the role is product-related.

• Example: "What do you know about Oracle Cloud Infrastructure (OCI)?" or "How would you design a high-availability database solution using Oracle products?"

4. Aptitude and Logic Questions

In some interviews, especially for entry-level roles, you may face logical reasoning and aptitude questions designed to evaluate your problem-solving approach.

Resources for Preparation:

• Grokking the Coding Interview and Grokking Data Structures & Algorithms can help you prepare for Oracle’s coding and algorithm questions.
• Grokking System Design can guide you through system design challenges you may encounter at Oracle.

In conclusion, Oracle interviews assess a wide range of technical and soft skills, so be prepared for in-depth coding, database queries, system design, and behavioral questions.
