"I have used the Agile software development methodology in several of my previous positions. I like this process because it is an iterative development methodology that requires a great deal of collaboration between all the stakeholders involved with a software development project. Before beginning work, the team holds daily standup meetings to review what was accomplished during the previous day and plan the upcoming activities. This provides the team with the opportunity to confirm that they are moving in the right direction and to catch any errors which may have occurred during the development process, correcting them before they have a greater impact on subsequent activities or the final product. My experience has been that the Agile methodology enables teams to deliver software products quicker, with greater accuracy, and higher quality."

If you mention Agile in your previous answers during the interview, you're likely to be asked about it in more detail in a subsequent question. As a senior software engineer, you should be intimately familiar with various development processes, including Agile, SCRUM, and Waterfall. Even if you have not used one of these processes and one of your previous positions, you should describe them and their advantages and some of the additional tasks they add to the development process. If you have thoroughly researched the organization before the interview, you will understand which of these processes they use and be prepared to answer questions about it.
