What was the length of a typical sprint in the software development projects on which you have worked?

This is an interesting question because it is using the term sprint, which has not been discussed up to this point. The interviewer is assuming that you understand this term due to your background in agile development. As a quick review, a sprint is one of the iterations which occurs during software development. You can define the term sprint when answering the question and then talk about the legs of a typical sprint. You may also assume that the interviewer is already familiar with the term and answer the question about the length of the sprint.

"As you're probably aware, a sprint within the context of agile is one of the iterations of the software development project. The length of a sprint depends on the complexity of the software development project and the product owner's expectations. Sprints can last as little as a few hours or as long as a week. It is important to keep the length of the sprints appropriate to the nature of the project so that agile principles are adhered to."
