Interview Process

The interview started with a brief introduction where I was asked about my background and experiences. The interviewer then presented the coding problem: “Robot Grid Distance Challenge,” which required finding the minimal distance for a robot to reach a target position in a grid.

I was given some test cases, and we discussed the problem constraints and requirements. I coded the solution in Python, focusing on optimizing for time and space complexity. Throughout the session, the interviewer asked probing questions to understand my thought process and approach to problem-solving.

After successfully implementing the algorithm, I explained my code line by line and addressed any concerns the interviewer had. We also discussed possible edge cases and testing scenarios. The interview concluded with an opportunity for me to ask questions about the team and company culture, which I found very enlightening. Overall, the experience was positive, and I felt that I aligned well with the company’s values and technical expectations.
