Interview Guides for Consulting Engagements

Interviews are the primary tool for understanding organizational reality. They reveal what actually happens (vs. what's supposed to happen), uncover pain points and workarounds, surface political dynamics, and build relationships with key stakeholders. Good interviews are disciplined and structured; poor interviews are rambling, biased, and generate unreliable insights. This skill covers designing, conducting, and synthesizing interviews.

Interview Types

Discovery/Diagnostic Interviews

Purpose: Understand current state, identify pain points, establish baseline understanding Duration: 45-60 minutes Frequency: 20-30 interviews across organization Who to interview: Cross-functional representatives—finance, operations, IT, customers, suppliers, frontline staff Question style: Open-ended, exploratory, hypothesis-generating Output: Pain point inventory, process understanding, organizational dynamics, hypothesis validation

Use when: Starting an engagement, need to understand lay of the land, validate scoping assumptions

Validation Interviews

Purpose: Test hypotheses, validate preliminary findings, pressure-test recommendations Duration: 30-45 minutes Frequency: 5-15 targeted interviews Who to interview: Key stakeholders affected by recommendations, subject matter experts Question style: More directive, testing specific assumptions Output: Refined recommendations, risk identification, refinement of approach

Use when: Have preliminary findings and want to pressure-test before refining recommendations

Expert/Deep-Dive Interviews

Purpose: Understand specialized area in depth Duration: 60-90 minutes Frequency: 3-7 interviews per domain Who to interview: Subject matter experts, senior practitioners, process owners Question style: Detailed, technical, exploratory Output: Detailed process understanding, technical requirements, constraints

Use when: Need deep expertise on specific area (e.g., detailed financial control requirements, complex IT architecture)

Executive Interviews

Purpose: Understand strategic context, get leadership perspective, test strategic fit of recommendations Duration: 30-45 minutes Frequency: 5-10 interviews with senior leaders Question style: Strategic, big-picture, business context Output: Strategic alignment, executive priorities, governance structure understanding

Use when: Engaging with C-suite or executive steering committee

Customer/Stakeholder Interviews

Purpose: Understand external perspective, customer needs, market dynamics Duration: 45-60 minutes Frequency: 5-20 interviews Who to interview: Current customers, prospective customers, partners, suppliers Question style: Exploratory, needs-focused Output: Customer requirements, market positioning, product/service strategy

Use when: Engagement involves customer experience, product strategy, or market changes

Question Design

Open-Ended vs. Closed Questions

Open-Ended Questions (Use 80% of the time)

What? How? Why? Tell me about...
"Tell me about how you currently process customer orders."
"What are the biggest challenges in your role?"
"How does this decision get made?"
Advantages: Respondents give detailed answers, reveals thinking, unexpected insights
Disadvantages: Takes longer, varies by respondent

Closed Questions (Use 20% of the time)

Yes/no or multiple choice
"Do you use the system every day?"
"What's your biggest pain point: speed, accuracy, or cost?"
Advantages: Quick, consistent, easy to compare across respondents
Disadvantages: Limits responses, misses nuance, can introduce bias

Better approach: Closed question followed by open follow-up

"Do you approve orders yourself?" [Yes]
"Tell me about your approval process. What does it look like?"

Question Funnel Technique

Start broad, get specific. Narrow as you go.

Example funnel for understanding approval process:

Broad entry: "Walk me through how an order gets approved in your area."
- Respondent provides overview
Specific funnel: "You mentioned it takes 2-3 days. Why does it take that long?"
- Narrow to timeline and root causes
Deeper probe: "When you say you're waiting for finance, who specifically do you wait for? What are they checking?"
- Narrow to specific bottleneck
Detail: "If you had to describe the ideal approval process, what would it look like?"
- Move to solution-oriented thinking

Probing Follow-Ups

When you get a surface-level answer, probe deeper.

Probing techniques:

| Technique | Example | When to Use | |-----------|---------|-----------| | Silent pause | [Ask question, pause 3 seconds, listen] | Get fuller response, let them think | | Clarifying probe | "Can you give me an example of that?" | Vague answers, need specifics | | Expanding probe | "Tell me more about that." | Interesting answer, want depth | | Chain probing | "Why? Why? Why?" (3x) | Get root cause, not symptoms | | Emotional probe | "How does that make you feel?" "What frustrates you?" | Emotional content, real impact | | Scenario probe | "Can you walk me through the last time that happened?" | Concrete example, not abstract | | Hypothetical probe | "What would happen if the system went down?" "What would ideal look like?" | Testing ideas, exploring options |

Example chain probing (getting to root cause):

Q: "Orders take too long to process."
P1: "Why does it take so long?" → A: "We have to wait for approvals."
P2: "Why does approval take so long?" → A: "Finance isn't always available."
P3: "Why isn't finance always available?" → A: "They're in meetings, or checking other things."
P4: "What's the bottleneck specifically?" → A: "One person signs off on all large orders; we're waiting for their bandwidth."

Root cause: Process single-threaded to one person (not lack of process, availability to meetings)

Leading Questions to Avoid

Leading questions bias responses toward your preferred answer. Avoid:

Bad: "The current process is inefficient, right?" Better: "Tell me about the current process and how you view it."

Bad: "Don't you think the system is hard to use?" Better: "What's your experience using the system?"

Bad: "We've heard from others that cost is the biggest pain point. Is that true for you?" Better: "What's your biggest pain point?"

Bad: "Would you prefer Option A (good things) or Option B (bad things)?" Better: "Here are options A and B [equal weight]. What are pros and cons of each?"

Interview Protocol

Standard interview structure is 50 minutes total:

Structure

Intro & Rapport (2 minutes)

Introduce yourself and the engagement
Clarify confidentiality: "What you share will be used to inform recommendations; I won't attribute comments to you in reports"
Establish rapport: Small talk, find common ground if possible
Set expectations: "I want to understand your perspective on X. I'll ask questions, take notes, and we'll wrap in 50 minutes. Does that work?"

Context Setting (3 minutes)

Briefly explain why you're interviewing: "We're trying to understand the order-to-cash process and identify opportunities to improve it"
Acknowledge their role: "You're [title]; you've been here [time]. Your experience in [domain] is valuable"
Confirm their willingness: "I appreciate you taking the time. Any questions before we start?"

Core Questions (30 minutes)

Ask 5-7 core open-ended questions
Use funnel technique: broad → specific
Follow-up with probing when appropriate
Let natural flow of conversation guide (don't feel locked to questions)

Probing (10 minutes)

Dig deeper on interesting/unexpected responses
Use chain probing for root causes
Explore scenarios: "What happens if...?" "What would happen if we changed...?"
Test any preliminary hypotheses gently

Wrap-Up (5 minutes)

"Is there anything I haven't asked that you think is important?"
"If you could tell the leadership team one thing, what would it be?"
"May I follow up if I need clarification?"
"Who else should I talk to?" (referral source for next interviews)
Thank them sincerely
Clarify next steps

Note-Taking Best Practices

During the Interview:

Structured template (top of page):
- Date, time, person's name/role, company/department
- Engagement name and purpose
- Interviewer name
Three-column approach:
- Left: Their key points (bullets, shorthand)
- Middle: Your observations/interpretations (can write during or after)
- Right: Questions for follow-up/later interviews
Verbatim capture:
- Put quotes in quotation marks for good quotes
- "We spend 40% of our time on exceptions"
- "Finance is the bottleneck"
- Useful for illustrating findings later
Real-time coding:
- Mark important points: ⭐ (key insight), ❌ (pain point), ? (unclear, needs follow-up)
- Allows quick scanning later
Emotion notes:
- Tone: frustrated, enthusiastic, cautious?
- Energy: high engagement or check-out?
- Helpful context later: "Finance leader seemed defensive about approval process"

After the Interview (within 24 hours):

Clean up notes (if handwritten, type up)
Fill in middle column: Your interpretations and questions
Add summary box at bottom:
- Top 3 themes they raised
- Top 2 pain points mentioned
- Key quotes
- Follow-up questions
- Referrals for next interviews
