Interview Process
The interview process began with a phone screen. The interviewer was quite friendly and explained the structure of the interview in brief. It started with some behavioral questions to get to know me better. After that, we moved on to the coding section where I was presented with the Robot Grid Distance Challenge. The interviewer asked me to write a solution, explaining my thought process as I went along.
I took a moment to think about the problem, ensuring I understood the requirements and constraints clearly. The challenge required me to calculate the minimum distance a robot could travel on a grid. I first wrote down the approach using a grid representation and then implemented a backtracking solution.
The interviewer was supportive, providing hints when I was stuck. Once I shared my complete solution, he asked me to optimize it further. I recognized that my initial approach was not efficient enough for larger grids and took a moment to analyze it.
After discussing potential improvements, I revised my solution to implement dynamic programming concepts. This time, I focused on reducing time complexity, which impressed the interviewer. We wrapped up the call with a few questions about my projects and experience at previous jobs. Overall, it was a positive experience with a good balance of technical challenge and conversation.
