2. What are some of the software design patterns that you use, and in what situations do you use them?
How to Answer
Interviewers ask you operational questions during an interview for a software developer's position with Google to determine how you complete the tasks required by this role. They also want to learn that your techniques are similar to those of the Google development team. Operational questions are best responded to succinctly and directly. You should always expect follow-up questions when a Google interviewer is asking about a specific task. This indicates that they have a special interest in the topic they are questioning you about.
Answer Example
"Throughout my career, I've tried several different software design patterns. Some of these were Singleton, MVC, and Iterator. However, the one I use the most is Template. This design pattern helps me code straightforwardly and accelerates the software development cycle. It also results in fewer errors and less debugging."
