Interview Process

The interview consisted of two main questions. The first involved handling streaming data of infinite length using a deque. The second question presented a dynamic graph where edges could be added and removed, requiring the candidate to find the number of strongly connected components after each operation. The optimal solution involves using a concatenation set; however, the candidate reverted to a data structure learned years ago and struggled to recall the optimal approach, ultimately implementing a brute-force BFS solution.

Technical Questions

  1. Data Stream Handling
  2. Graph Theory - Strongly Connected Components

Tips & Insights

The candidate emphasized the importance of being familiar with various data structures and algorithms, suggesting that a solid understanding of optimal solutions is crucial for success in technical interviews.
