Sample answer is:
We use Agile methodology for software development. We have scrum team of 7 team members including Dev engineers, QA engineer, Product manager and Architect.
We develop things in an iterative mode. In the beginning we groom stories with Product manager and design them with Architect. Once the design is ready and reviewed, we develop software with Test Driven Development manner.
We develop unit tests along with the code that we write. Once coding is complete, we perform code review and check in code. Once code is checked in, the build starts. During build process unit tests, integration tests and automated tests run.
After the build our application is ready for deployment.
