Interview Prompt
Given grid = [[0] * 3 for _ in range(3)], set grid[1][1] = 9 and print grid. (This works because each row is a distinct list, unlike the [[0]*3]*3 shallow-copy trap.)
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write your python solution with real code execution
- Get instant feedback and a hire/no-hire decision
