Graph Interview Problems
Graph problems are among the most versatile and challenging in coding interviews. They appear in many forms — from social networks to map routing to dependency resolution. Understanding graph traversals and common algorithms is critical for senior-level interviews.
Why Graphs Problems Matter
Graph problems are especially common in senior and staff-level interviews. They test your ability to model real-world problems as graphs and apply the right algorithm. Companies like Google and Meta heavily favor graph questions.
Key Patterns to Master
BFS
DFS
Topological Sort
Union Find
Dijkstra's Algorithm
Cycle Detection
Example Problems You'll Practice
Interview Tip
Always clarify the graph type: directed vs undirected, weighted vs unweighted, cyclic vs acyclic. Choose BFS for shortest path in unweighted graphs, DFS for exploring all paths or detecting cycles.
