Mid-Level Java Developer

This test targets mid-level Java developers and includes a balanced mix of algorithmic coding challenges and theoretical questions. The coding problems cover common technical competencies such as string manipulation, array operations, algorithm optimization (e.g., Kadane’s algorithm, two-pointer technique), and working with Java collections. The 3 theoretical questions test understanding of Java syntax, performance characteristics, and OOP principles. Difficulty is calibrated to filter out junior candidates while surfacing those with strong practical coding ability and core Java knowledge.
