Design a Two-Player Chess Game Engine Object-Oriented Design Interview

Design a chess engine that models a board and pieces, validates legal turns and moves, records move history, and detects check, checkmate, stalemate, resignation, and forfeit.

Mock Interview with AI

1. Problem Statement

Design a two-player chess game engine that enforces alternating turns and legal moves, records history, and detects check, checkmate, stalemate, resignation, and forfeit.

2. Live Coding Format

Work in the provided coding workspace while explaining your decisions to the live interviewer. Validation may use inline tests, examples, comments, or a verbal walkthrough.

3. Key Focus Areas

1
Board, square, piece, player, and game responsibilities
2
Piece-specific movement versus full legal-move validation
3
Check, checkmate, and stalemate detection
4
Move history and special-rule extensibility

4. What Strong Candidates Should Demonstrate

✓Separate piece movement rules from whole-game move legality.
✓Model board ownership, turns, move history, and terminal game states.
✓Validate moves without corrupting board state when simulating check.
✓Reason about extensible handling of special moves and rule variants.
