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
