Online Assessment (OA)

The Oracle Software Development Engineer (SDE) interview process typically focuses on evaluating a candidate's problem-solving skills, coding abilities, system design knowledge, and behavioral aptitude. Here’s a breakdown of the process:

1. Online Assessment (OA) Conducted via platforms like Hackerrank or Codility. Format:

   • 2-3 coding questions based on Data Structures and Algorithms (DSA).
   • Topics may include arrays, strings, trees, graphs, dynamic programming, and sorting algorithms.
   • 1-2 problems may include optimization and time complexity considerations. Duration: ~60-90 minutes. Tip: Practice LeetCode-style problems with an emphasis on DSA and problem-solving.

2. Technical Interviews (2-3 Rounds) Each round evaluates different technical skills and may include live coding.

   Round 1: Data Structures and Algorithms (DSA) Involves solving medium to hard-level coding problems in real-time. Examples:

   • Solve problems using binary trees, graphs, sliding window, or hashmaps.
   • Time and space complexity analysis. Round 2: Problem-Solving and Optimization More focus on advanced DSA topics like Dynamic Programming, Greedy Algorithms, or Trie. The interviewer may ask you to optimize the solution step by step. Behavioral/HR Round This round evaluates your communication skills, teamwork, and alignment with Oracle’s values.

Solve problems using:

• Binary trees
• Graphs
• Sliding window
• Hashmaps
