Example

“I would design a microservices architecture where a front-end service captures page views and sends them to a message queue. From there, a processing service would aggregate the data and store it in a NoSQL database for quick retrieval. I would also implement monitoring to ensure the system can handle spikes in traffic.”

3. Implement a DAG generator.

This question assesses your coding skills and understanding of data structures.

How to Answer

Explain your thought process before diving into the implementation. Discuss how you would handle edge cases and ensure the generator is efficient.

Example

“I would start by defining a class for the DAG that includes methods for adding nodes and edges. I would ensure that when adding an edge, it checks for cycles to maintain the properties of a DAG. The generator would use depth-first search to traverse the graph and return the nodes in topological order.”
