Interview Process

I had a coding and behavioral interview with Google. The interview started with behavioral questions about my previous projects and how I handled challenges. I shared my experience with a team project where we faced tight deadlines and had to adapt our plans on short notice.

After the behavioral section, we transitioned to the coding segment. The interviewer presented a coding challenge involving data structures and algorithms. I was tasked with solving a problem related to binary trees and efficient searching. I outlined my approach, discussed the time complexity of different algorithms, and explained why I chose a specific one for this problem. The interviewer seemed satisfied with my thought process and encouraged me to proceed.

I wrote the code in a shared editor, and they prompted me with questions about edge cases and optimizations. Overall, I felt good about the interview and its flow. They mentioned that they would get back to me soon regarding the next steps.

Technical Questions

  1. Binary Tree Search (Tree, Binary Search)
  2. Data Structure Design (Hash Table, Reservoir Sampling)

Tips & Insights

  • Be prepared to discuss your thought process in detail during coding challenges.
  • Practice explaining your code and considerations for edge cases and optimizations.
