What Is an Informational Interview?

An informational interview is a short, informal meeting where a person interested in a particular career or industry talks with someone already working in that field. Unlike a job interview, this conversation isn’t about getting hired but about learning firsthand what the job entails, what skills are needed, and what the work environment is like. For example, if you’re considering a career in public relations, you might reach out to a PR specialist to ask about their daily tasks, challenges they face, and how they entered the profession.

These conversations can take place in person, by phone, or via video call, and they are usually initiated by the person seeking information. This method is a powerful way to gain realistic insights that job descriptions or websites cannot provide.

How Does the Timing of an Informational Interview Work?

The ideal duration for an informational interview is between 20 and 30 minutes. This period strikes a balance between allowing enough time to ask meaningful questions and respecting the professional’s busy schedule. When setting up the interview, clearly communicate the expected length to make it easier for the other person to agree.

Here is a typical flow of a 30-minute informational interview:

1. Introduction and small talk (5 minutes): Start with a brief introduction about yourself and thank the person for their time.
2. Main questions (15-20 minutes): Ask your prepared questions about their career path, daily responsibilities, industry trends, and advice.
3. Closing and next steps (5 minutes): Wrap up by asking if they have any additional advice, whether you can stay in touch, and thank them again.

For example, if you have 30 minutes scheduled, you could say: “Thank you for meeting with me. I’ve prepared a few questions about your role in environmental consulting, and I want to be mindful of your time, so I’ll keep it to about 30 minutes.” For guidance on structuring these conversations, see How to Structure an Informational Interview.

Why Is the Length of an Informational Interview Important?

The length of an informational interview matters for several reasons. First, professionals are often busy, and a shorter, well-defined meeting makes it easier for them to say yes. A clear 20-30 minute commitment feels manageable during a lunch break or between meetings, whereas asking for an hour might be intimidating.

Second, a concise meeting encourages focused, relevant discussion. When time is limited, both parties tend to concentrate on the most important questions and answers, keeping the conversation productive. For instance, an interviewee might share specific challenges in their job or recommend skills to develop, rather than giving lengthy, general answers.

Finally, respecting the agreed-upon timeframe shows professionalism and appreciation. If you overrun the time, the professional might feel pressured, which could reduce the chance of future help. To plan a respectful meeting, be clear about the interview length when requesting it (see How to Request an Informational Interview) and be attentive to time during the conversation.

What Are Common Terms People Mix Up With Informational Interviews?

Informational interviews are sometimes confused with other types of professional meetings. Understanding the differences helps set the right expectations:

• Job interview: A formal meeting where an employer evaluates a candidate for a specific position. It usually lasts longer (often 45 minutes to an hour or more) and focuses on qualifications and hiring decisions.
• Mentorship: An ongoing relationship where a more experienced person provides guidance and support over time. Mentorship can involve multiple meetings and long-term career advice.
• Networking chat: Less formal and often more social, networking chats can be brief or extended but don’t always focus on specific career insights.
• Career coaching session: A paid or formal service providing professional guidance on career goals, job search strategies, and skill development.

Knowing these differences ensures you approach informational interviews with clear goals and appropriate timing. To communicate what an informational interview is to contacts, see How to Explain Informational Interviews.

How Can You Prepare to Make the Most of a 20-30 Minute Informational Interview?

Preparation is key to making the most of your limited time. Here are steps to prepare effectively:

1. Research the person and their company: Understand their role, background, and organization so your questions are relevant.
2. Prepare focused questions: Limit yourself to about 5-7 questions, prioritizing the most important ones.
3. Practice concise introductions: Have a brief summary of who you are and why you’re interested in their field, such as: “I’m a recent graduate interested in nonprofit fundraising, and I’m eager to learn about your experience in this area.”
4. Organize your questions into categories: For example,

1. Plan to take notes: Bring a notebook or use a device to jot down key points.

By preparing this way, you can keep the conversation focused and respectful of time. For more question ideas, see What to Ask in an Informational Interview.

What Should You Do After the Informational Interview?

Following up is an important step to build relationships and show gratitude. Here’s what to do:

• Send a thank-you note within 24 hours: Use email or a handwritten note to express appreciation. Include a specific detail from your conversation, like: “Thank you for sharing how you manage client relationships. That insight was very helpful.”
• Reflect on what you learned: Review your notes and identify how this information affects your career plans or next steps.
• Stay in touch, if appropriate: If the professional invited you to keep in contact, send occasional updates or relevant articles. Don’t overdo it; maintain a respectful pace.
• Consider asking for introductions: If you want to expand your network, you might ask, “Do you know others in this field I could speak with to learn different perspectives?”

How Do You Schedule an Informational Interview to Fit the Ideal Time?

Scheduling an informational interview requires clear communication about the expected time commitment. Use these tips:

• Be specific in your request: For example, say, “Would you be willing to meet for 20-30 minutes next week for a quick conversation about your career in software development?”
• Offer flexible options: Suggest phone, video call, or in-person meetings to accommodate the professional’s preferences.
• Propose several dates and times: For example, “I’m available Tuesday afternoon or Thursday morning, but I’m happy to work around your schedule.”
• Confirm the appointment: Send a brief reminder a day before the meeting and restate the time and format.

Here’s a sample request email:

Dear [Name], I admire your work in marketing, and I’m exploring career opportunities in this field. Would you be open to a 20-30 minute informational interview next week? I’d appreciate learning about your experience and any advice you can share. Please let me know what time works best for you. Thank you for considering my request. Best regards, [Your Name]

Clear communication about the brief duration helps professionals say yes without feeling overwhelmed. For more tips, see How to Schedule an Informational Interview.

How Can You Handle Variations in Interview Length?

Sometimes an informational interview may be shorter or longer than planned. To manage this:

• If the interviewee is running short on time: Prioritize your top 3 questions and be ready to end early. You can say, “I understand your time is limited, so I’ll focus on a few key questions.”
• If the conversation is flowing and longer: Politely watch the clock. When 30 minutes approaches, say, “I don’t want to take more of your time, so I’ll wrap up now unless you’d like to continue.”
• If the person is very talkative: Guide the conversation gently by redirecting to your questions. For example, “That’s very helpful. I also wanted to ask about…”

Being mindful of time keeps the meeting professional and increases the chances of future support.
