Software design patterns are repeatable solutions to commonly occurring issues in software development. It is a general outline of approaching software development rather than a specific solution or piece of code. It can be thought of as a template. Using design patterns allows software developers to quickly create a development plan and outline for the software program. As a senior software engineer, you should have several designs you typically use when beginning a software development project. These will very likely be associated with the common types of software you work on.

"I am a big believer in software design patterns. Starting with a template makes it much easier to create a software development plan and a strategy for the code I am about to write. Some of the more common design patterns I employed are Singleton, Factory Method, Observer, Builder, and Strategy. I select the most relevant pattern for the type of software I am developing and which will lead to the best outcomes in the shortest amount of time."

Software design patterns are common to this profession, so you should anticipate being asked this question during an interview. Having some examples of how you use these prepared will help you quickly respond to the interviewer's question. Better yet, use the information you discovered during your research to create examples that align with the current development methodologies of the organization's software development team. The closer your answers align to their current operations, the more likely you will be perceived as a good fit and offered the position.
