Interview Process
The Uber tech phone screen consisted of a single coding question that asked to solve the Robot Grid Distance Challenge. I was given a grid where a robot could move in four directions (up, down, left, right) and had to calculate the shortest distance to a target coordinate.
To approach the problem, I started by visualizing the grid and how the robot could traverse it. I discussed my thought process with the interviewer, explaining my plan to use breadth-first search (BFS) for the traversal because it would guarantee the shortest path in an unweighted grid.
I also walked through the edge cases, like when the grid was empty or if the target was unreachable. After coding, I ran through different test cases to demonstrate my solution’s correctness. The interviewer seemed satisfied with my explanation and solution. Overall, the interview felt structured, and I appreciated the focus on problem-solving rather than trick questions.
