Interview Process
During my phone screen with Uber, I encountered the Robot Grid Distance Challenge. The challenge required me to calculate the shortest path a robot can take in a grid with certain obstacles. The interviewer was quite friendly and encouraged me to explain my thought process as I progressed through the solution.
I initially described a brute-force approach involving recursive calls to explore all possible movements. The interviewer pointed out its inefficiency and prompted me to consider more optimal solutions. After some back and forth, I suggested implementing a BFS approach to find the shortest path, which seemed to resonate well. I wrote code to demonstrate the BFS algorithm, checking my logic and refining my thought process based on the interviewer’s feedback. The session concluded with a few behavioral questions, which were standard fare for most software engineering interviews nowadays. Overall, it was an engaging experience, and I’m hopeful for a positive outcome.
