Interviewing with Confidence Interview Preparation and Research

Understanding the Company's Business Model and Revenue Streams

Feeling lost when asked how a company makes money in an interview? Use the 'trace a dollar' trick: follow one customer from their problem to their payment, and you'll see exactly how any business earns money — no finance background needed.

Focus and Planning

How to Map Where Money Comes From

  • 01
    Find the Person Who Hurts Most Figure out exactly who has a problem that gets much worse if your company stops working. This shows you where the money really comes from.
  • 02
    Follow the Pain to the Payment Trace every step from a customer's first annoyance to when they pay you. See exactly what difficulty your company removes to earn that money.
  • 03
    See the Money Keep Coming Back Track how one initial purchase leads to more payments later, like ongoing support fees or needing to buy refills. This shows you the real worth of a customer over time.
  • 04
    Costs vs. New Income Ideas Compare how much money is spent just keeping things running versus how much is spent finding new things to charge customers for. This reveals the company's true plan for getting bigger.

The Business Confusion

The room suddenly feels way too hot when the person interviewing you leans in and asks, "So, how do we actually make money?" The question is asking you to explain the business model: how the company turns a product or service into profit. But the slides just look like blurry noise. You see the colors, but you can't see the money. It's a specific kind of dizzy spell, a mental fog where terms like "recurring revenue" and "unit economics" sound like nonsense instead of a clear path forward.

The usual advice is to read the yearly financial report, but for most people, a giant report full of numbers is just something to put on a shelf. It gives you tons of data but hides the human story behind complicated money words, making you feel more confused than when you started.

To get how any business works, you need to stop trying to remember numbers and start following the real journey of one dollar from a customer's pocket to the company's bank account.

What Is a Business Model?

A business model describes how a company creates value for customers and converts that value into revenue. It answers three questions: who pays, what they pay for, and how that money flows through the organization. Before any interview, knowing these three answers puts you ahead of most candidates.

Common business model types include subscription (customers pay a recurring fee), transaction-based (one-time product sales), advertising (free users plus ad revenue), and marketplace (connecting buyers and sellers for a percentage). Most companies blend two or more of these. A SaaS company might charge a monthly subscription fee and earn additional revenue from onboarding services.

Revenue streams are the individual categories within that model: a subscription fee, an overage charge, a professional services invoice. Understanding both the business model and its specific revenue streams lets you speak to where the company is growing, where it's vulnerable, and how your work fits into keeping it running.

The Science of Understanding Business Models

What's Happening in Your Brain

When you look at a spreadsheet or a complicated money report and your mind just goes blank, it’s not just boredom—it’s your brain hitting a wall. To your brain, using confusing money words or looking at complex numbers feels like a danger signal, and it kicks in a natural defense mode.

Why This Happens

Your brain is built to spot patterns. When it sees abstract ideas like confusing language or complicated data that don't have a real, physical picture, the alarm center (the Amygdala) sends out a threat signal, releasing stress hormones. This reaction treats the lack of clarity like a physical danger, causing that blank, stuck feeling in your head.

What the Research Shows

Harvard cognitive psychologist George Miller found that working memory can hold roughly seven pieces of information at once, and later research suggests the ceiling drops closer to four items when the material is complex or abstract (Miller, Psychological Review, 1956). When a financial report stacks 50 data points in front of you, your brain isn't being lazy. It's hitting a hard biological wall.

What This Means for Your Work

The thinking part of your brain (the Prefrontal Cortex), which is like the boss, gets quickly overwhelmed by too much raw, unorganized information. It can only handle so much at once. This overload causes the boss to shut down temporarily to save energy. As a result, you might know the facts, but you lose the ability to logically explain or make a plan based on them.

Why a Quick Fix Works

You can't force yourself to focus when your brain is in this state. You need a quick switch to get back on track. By making your brain create a real-world picture or simple comparison, you tell the alarm system that things are safe. This lets your thinking part come back online so you can focus on what the business does instead of just looking at scary numbers.

"Your brain chose to protect you instead of letting you plan."

Quick Fixes for Different Job Roles

If you are: The Creative Person
The Problem

You feel like you don't belong because you see your work as creative, and the money side seems like a confusing wall of math.

Your Quick Fix
Physical Action

Take a blank piece of paper and draw a simple stick figure (the customer) and a box (the product). Draw one arrow showing the customer giving a dollar bill to the box to make it yours.

Thinking Shift

Stop using the word "Revenue" and start using the word "Value." Ask yourself: "What specific problem does my design or writing fix that makes a stranger willing to pay for it?"

Digital Look

Go to the company’s website and look at the "Pricing" page. Ignore the dollar amounts for now and just look at the names of the plans (like Basic, Pro, Premium) to see who they think their customers are.

The Result

You stop feeling like just someone doing a task and start seeing how your creative choices directly lead to a customer choosing a certain price level.

If you are: Someone New to This Industry
The Problem

It’s hard to find the real purpose of the business because the product is digital or hidden, unlike the physical items you dealt with before.

Your Quick Fix
Physical Action

Pick up a physical item on your desk to stand in for the company's software or service (like a pen). Spend 60 seconds out loud describing how that "pen" gets delivered to a customer's screen.

Thinking Shift

Use the "Switch." Tell yourself: "In my old job, we made money by selling [Physical Thing]; in this job, we make money by selling [The Digital Version of that same help]."

Digital Look

Find a "Product Demo" or "Explainer Video" for the company’s software on YouTube. Watch it at faster speed to see the exact moment the user understands the benefit they paid for.

The Result

You stop trying to physically hold the product and start realizing the "value" is the time or stress you save the customer.

If you are: New to the Job Market
The Problem

You can define business words from a book, but you don't get the "real reason" why a customer would choose this company over a cheaper one.

Your Quick Fix
Physical Action

Stand up and spend 60 seconds trying to "sell" the product to an imaginary friend, focusing only on why it’s better than the free option.

Thinking Shift

Ask the "Pain Point Question": "If this company suddenly disappeared tomorrow, what is the one thing its customers would miss the absolute most?"

Digital Look

Open a review site like G2 or Trustpilot, or even Reddit. Read exactly three "1-star" reviews of the company’s main rival to see what problem your company is actually solving.

The Result

You switch from reciting definitions you memorized to understanding the real competition reason that drives the business every day.

What the Experts See

Important Reality Check

The quick action step is about translating. It means taking those huge, scary business terms and changing them into a simple story: "Someone who has this exact problem gives us $50, and we give them this exact fix in return." It means asking the sales team what customers complain about or asking a manager what happens if a client leaves. You are looking for the real "why" behind the money.

Research on candidate behavior shows that 54% of job seekers say they research every company before applying, but most focus on salary (74%) and benefits (70%) rather than the business model. The candidate who can explain how the company earns money — and connect their own work to that — is the exception, not the rule. That gap is an opening.

The Wrong Way: "Just Read the Numbers"

Telling a creative person or a teacher to read a 100-page legal financial report to "get the business" is like telling someone who wants to cook to read a textbook on chemistry first. It gives you raw data with no context. It’s written to meet a legal requirement, not to help you do your job better. Doing this won't make you smarter; it will just make you more tired and more convinced you don't belong in the business world.

The Smart Way: Taking Action

Taking big, confusing business ideas and turning them into a simple story: "Someone with this specific problem gives us $50, and in return, we give them this specific solution." It means asking the sales team what customers complain about or asking a project manager what happens if a client cancels. You are looking for the true "reason" behind the money.

Once you have the right mental model, knowing where to look makes all the difference. The fastest sources are the pricing page (to understand who pays and how much), the investor relations page or Crunchbase profile (to see reported revenue sources), and reviews on G2 or Glassdoor (to hear what customers say the company delivers). For a step-by-step breakdown of the best research sources, see our guide on how to research a company beyond its homepage.

The Hard Truth You Must Face

If you have asked three different managers how the company actually makes a profit and you get three different vague answers full of buzzwords like "synergy" or "ecosystems," the problem is with the company culture. You aren't just confused—you are working in a Place Where Things Are Kept Secret.

If you have been there for months and the business model still feels like a secret code you can't break, you need to stop trying harder to understand a mess that doesn't make sense. If the leaders keep things "vague" on purpose, they might be hiding a lack of direction or a shaky foundation. You can't build a career on a foundation you can't see. Stop trying to "study more" and start looking for your next opportunity—one where the value you create is clear, measurable, and real. If the "why" is missing, your future there is missing, too. Plan your move to a place where the value you create is visible, measurable, and real.

Quick Questions: Getting Past the "Business Talk" Block

Why does my role need to understand the business model?

It's necessary for everyone. Your salary is paid by the company's ability to make a profit.

When you know how money moves through the business, you can explain how your specific job helps that money move faster or stay with the company longer. This changes you from just an expense to a valuable person who gets the big picture, in any role, in any department.

Is a simple explanation too basic for an interviewer?

No, simple is better.

Most interviewers are tired of hearing candidates repeat buzzwords like "synergistic monetization" when they don't know what they mean. Explaining how the business makes money in plain language proves you have rare business acumen: the ability to see things from the customer's view and the owner's view at the same time.

How do I quickly research a company's business model before an interview?

Start with the pricing page: the plan names tell you who they sell to. Then watch the product explainer video to see exactly when a customer decides to pay. For public companies, the investor relations page gives a plain summary of revenue sources. For startups, Crunchbase shows what problem investors are betting they're solving. For a deeper framework, see our guide on how to research a company beyond its homepage.

What is a simple example of a business model I can use in an interview?

Take Spotify: a free user listens with ads (ad revenue); a premium user pays $11.99/month to remove ads (subscription revenue). The premium tier is the core business model. Use the same framing for the company you're interviewing at: who are the free users, who are the paying users, and what pain makes upgrading worth it?

What if I still can't figure out how the company makes money?

Stop trying to understand it from reports alone. Ask the sales team what customers complain about when evaluating the product. Read three 1-star reviews of their closest competitor on G2 or Trustpilot. Check their LinkedIn company page for recent announcements. If the business model is still unclear after all that, that's a signal about the company's own internal clarity, not your ability to understand it.

Take Control

Truly understanding how a business makes money is the difference between just having a job and actually knowing how to build something successful.

Don't just ride along in your career; take charge by learning exactly how value is created.

When you can clearly explain how a company turns a product into profit, you move from an employee who can be replaced to the strategist who makes any organization sharper.
