Interview Process

The coding question for the phone screen was about a Robot Grid Distance Challenge. The interviewer provided a problem statement where a robot is supposed to find out the shortest distance between two points on a grid while avoiding obstacles. I discussed my thought process with the interviewer and talked about different approaches like Breadth-First Search (BFS) and Depth-First Search (DFS). After explaining my choice of algorithm, I wrote the code in Python. The interviewer asked clarifying questions throughout, and I made sure to test my function with sample inputs. They seemed pleased with my problem-solving approach and coding skills. I concluded the interview by asking insightful questions about the team culture and ongoing projects, which garnered positive feedback. Overall, it was a good interaction and a fair chance to showcase my skills.

Technical Questions

  1. Robot Grid Distance Challenge (BFS, Grid)
  2. Fibonacci Tree Path Calculation Using Preorder Numbering (DFS, Binary Tree, Math)
  3. Tree Distance Sum Problem (Tree, Dynamic Programming)

Tips & Insights

  • Discuss your thought process openly with the interviewer.
  • Be prepared to explain your choice of algorithms and data structures.
  • Testing your code with sample inputs can demonstrate thoroughness.
  • Asking about team culture and projects can leave a positive impression.
