Frequently Asked Questions
What is graph in data structure interview questions?
The graph is a data structure consisting of vertices and edges that connect two vertices. Vertices can also be referred to as nodes. The set of vertices is defined as a set V, and the set of edges is defined as E.
How to approach graph interview questions?
Graph interview questions are generally considered tough questions. First of all, completely understand what the problem is trying to say. Most often, the question does not directly specify that the problem is a graph problem. This has to be inferred, and this will come with practice.
Are graphs asked in coding interviews?
Graphs are very often asked in coding interviews. Most of the top tech companies, such as Google, Uber, Apple, Netflix, etc, ask graph questions a lot. In fact, google asks graph problems the most. They are also asked in the coding assessment round of these companies.
How can I get better at answering graph interview questions?
Graphs are very often asked in coding interviews. To ace the coding interviews, one has to do graphs in depth. The problem-solving ability to solve graph problems comes automatically with practice, hence the best way to become good at graphs is practice.
