What are some of the software design patterns that you use, and in what situations do you use them?

Interviewers ask you operational questions during an interview for a software developer's position to determine how you complete the tasks required by this role. They also want to learn that your techniques are similar to those of their current development team. Operational questions are best responded to succinctly and directly. You should always expect follow-up questions when an interviewer is asking about a specific task. This indicates that they have a special interest in the topic they are questioning you about.
