Fifth: Use Us and We…
Yes, it's an interview and you hardly know these people. But at the same time, what is the harm in saying "And how would we handle that situation?" Instead of "And how do you handle that situation?" People like collaborators and collaborators use inclusive language. So strive to reduce any "us and them" mentality. If you're uncomfortable with the idea of being familiar so early on, then work to eliminate any group references. For instance in the previous example, "How would that situation be handled?" would work just fine.
Another aspect of being a collaborator is the ability to handle transitions. And interestingly, most organizations are in a constant state of transition — or seem to be to the people employed there. So highlighting your ability to handle transition phases in your work life can be very helpful to a stressed supervisor who is looking at hiring a new employee or filling a new position.
From the hiring organization's perspective, the job-filling process is a stressful experience. In offering an opening to someone, supervisors worry if they are making the right decision, if the relationship is going to succeed or if they are missing out on someone better suited for the job. Your goal is let the interviewer know that you are an enthusiastic, relaxed, confident and prepared applicant who wants to be part of their team. This puts the everyone in the interview at ease, highlights you from your fellow applicants and will make the entire experience more enjoyable for you. And that enjoyment will bring you a new level of confidence that will be immediately apparent to any potential employers.
