Interview Process

During the technical phone screen, I was presented with the Robot Grid Distance Challenge. The problem required calculating the minimum steps for a robot to move from its starting coordinates to its destination on a grid. I was expected to solve the problem on the spot and explain my thought process.

I began by outlining my approach, suggesting the use of a breadth-first search (BFS) strategy to minimize distance and explore all possible paths. The interviewer then presented various edge cases, such as the robot being at its destination or encountering obstacles. I had to adapt my BFS implementation to handle these scenarios, which tested my problem-solving skills under pressure. Overall, I felt confident in my performance.
