Interview Process

I had my technical phone screen with Uber. The interviewer was friendly and made me feel comfortable. We started off with a quick introduction about my background. Then, he moved on to the coding question.

The question was about finding the shortest path in a grid using a modified version of the Breadth-First Search (BFS) algorithm. I was asked to optimize my solution after the initial implementation. He emphasized understanding the time complexity and space complexity of my approach.

After writing the solution, I explained my thought process thoroughly. The interviewer provided a few hints to guide me through. I was also asked a couple of behavioral questions towards the end. Overall, I felt that the interview went well, but I’m still anxious about the outcome.
