Interview Process

I recently had a tech phone screen with Uber. The interviewer was very friendly and started off with a brief introduction about himself and the company. Then, he asked me to introduce myself and talk about my projects and the technologies I’ve worked with.

The coding problem presented was the “Robot Grid Distance Challenge,” where the task was to find the shortest path in a grid where a robot can only move right or down. I explained my thought process as I approached the problem, discussed possible approaches, considered edge cases and efficiency, and initially implemented a recursive solution. I then optimized it using dynamic programming to reduce the time complexity. After completing the coding task, the interviewer followed up with questions about optimization techniques and how I would handle larger grids. Overall, it was a positive experience, and I felt I was able to showcase my skills well.
