Summary

Pair programming round at Shopify for a frontend role. The task was to build a word guessing game together with the interviewer, which sounds fun until you're actually doing it live and second-guessing every component decision you make.

Suggested Approach

Start by clarifying requirements and constraints with the interviewer, then outline a minimal viable game (e.g., 5-letter word, 6 guesses) before coding. Build incrementally, testing each piece, and narrate your thought process while being open to feedback and trade-offs.

Pro tip: Treat the interviewer as a collaborator: ask for their input on ambiguous decisions and adapt your plan based on their feedback, demonstrating adaptability and teamwork.

1. Clarify Requirements

Ask questions to define the game scope: word length, number of guesses, feedback mechanism (e.g., color-coded letters), and any constraints (e.g., no external libraries).

2. Outline Architecture

Sketch a high-level plan: data structures (word list, game state), components (input, grid, keyboard), and state management (e.g., React state or vanilla JS).

3. Implement Core Logic

Code the game logic first: word selection, guess validation, and feedback generation (correct letter/position, correct letter/wrong position, absent).

4. Build UI and Integrate

Create the UI components and connect them to the game logic, ensuring the interface updates correctly with each guess.

5. Test and Refine

Test edge cases (e.g., duplicate letters, invalid words) and discuss potential improvements or trade-offs (e.g., performance, accessibility).

Key Points to Mention

  • Clarifying questions to resolve ambiguity (e.g., word source, game rules, UI expectations).
  • Trade-offs between using a framework (React) vs. vanilla JS, and between simple vs. robust state management.
  • Incremental development: start with a minimal working version, then iterate.
  • Handling edge cases like duplicate letters in feedback logic.
  • Testing strategy: unit tests for logic, manual testing for UI.
  • Communication and collaboration: thinking aloud, seeking feedback, and adapting.
