Hiring managers are looking for someone who will solve a problem for them, whether it's filling a gap in a specific team or department or literally fixing a problem. Restate the problem as you understand it. Your interviewer will appreciate your level of interest and engagement. And you'll have valuable information. Remember to come back to the problem or problems during your interview.
Many technical people are uncomfortable in the role of interviewer.
By helping to frame the interview in terms of problem and solution, you're helping them to conduct a successful interview. For example, an interviewer may ask you a question about your Java experience. Describe your experience and then explain how you could apply it to their problem. This shows you're a solution. Use anecdotes and stories.
