Interview Process

The technical phone screen focused on a challenging problem regarding robot grid distance. I was asked to implement a function that calculates the shortest path a robot could take based on a given grid with obstacles. I began by breaking down the problem and discussing breadth-first search (BFS) as a viable solution.

The interviewer prompted questions about edge cases and performance, leading to a deeper conversation about potential optimizations. I walked through my thought process while coding, highlighting how I would handle obstacles and various input scenarios. Overall, it felt productive, with positive reinforcement from the interviewer throughout the problem-solving process.

After the technical portion, I was asked behavioral questions focusing on teamwork and project experiences. I shared specific examples from my past roles, reflecting on challenges and successes I encountered. The conversation flowed naturally, allowing me to express my fit for the company culture.
