How to Prepare for a Consulting Job: Skills, Tools & Habits

Becoming a real consultant takes a lot more than passing an interview.

There, I said it. 

The people who actually break in start acting like consultants long before they ever get the title.

They break problems into clear steps. 

They deliver when the pressure is high.

They build habits that show up in every conversation with recruiters and in every project they join later on.

If you want to build that same foundation, this guide will show you how to:

  • Understand what consultants really do day to day
  • Develop skills you can practice right now
  • Build habits that make interviews and projects feel natural
  • Get comfortable with the tools consultants rely on every day

Let’s get started. 

What Consultants (Really) Do Daily Projects

Most people think consultants spend their time sharing big ideas or fixing slides.

That is only a small part of the job. The real work shows up when things are messy. 

You sort through unclear data and transform it into something the client can use. 

Deadlines are also tight, so you keep things moving and bring structure so everyone knows the next step.

That is what makes clients trust you and teams rely on you.

I see this every week at High Bridge Academy when we train candidates who are serious about breaking into the field. 

The sooner you start practicing these exact responsibilities, the sooner you stop preparing for a fantasy version of consulting and start training for the reality of the job. 

When interviewers notice that mindset, they take note. 

And when you join your first project, you walk in ready, not like someone who still needs to be taught the basics.

But understanding the role is one thing. 

Now let’s talk about the skills that will make you stand out before you even get hired:

Build These 5 Skills Before You Even Get Hired

Seeing what the job really involves is valuable, but it is not what will set you apart.

If you want to stand out, you need to start building the core skills now, long before you walk into an interview.

These are the exact drills I give to people I coach at High Bridge Academy, because they have proven effective.

1. Structure Your Thinking (Before You Speak)

One of the first things that separates a strong consultant from someone who is just “smart” is how clearly they speak under pressure.

Clarity builds trust. When you discuss a topic in a structured manner, managers know you understand the issue. 

Clients feel you can lead them to a solution.

McKinsey and BCG both train their new hires on what is called top‑down communication or the Minto Pyramid Principle

It is simple but powerful.

You start with your main answer first, then back it up with supporting points. This is the opposite of how most people speak, where they ramble through context and hope the listener figures out the main point.

Here’s why it matters:

  • Studies on information retention show that audiences remember structured messages 40% more clearly than unstructured ones.
  • In consulting, managers are often reviewing multiple workstreams at once. If they need to “dig” for your point, they will assume you are not ready.

So, how can you train this skill right now?

  • When someone asks you a question in class or at work, pause for two seconds before speaking. This short pause gives your brain time to frame your answer.
  • Write down your thoughts in three bullet points before you speak, even if it’s just in your head.
  • Lead with the headline: “Here’s what I see…” or “Here’s what’s driving the issue…”
  • Then walk them through your bullets one by one.

Example in action:

Rambling:

“Well, the project timeline has been kind of tight, and we’ve had some trouble with the data, and also there was an issue with roles, and the client hasn’t given us what we need, so we’re running late.”

Structured:

“Three things are causing delays: missing data access, unclear roles, and pending input from the client. Let me break those down.”

Notice the second version? 

It sounds decisive. 

It sounds like someone who knows what matters.

My pro tip:

Record yourself answering a practice case or even a simple question from a friend.

Play it back and ask: “Could someone take action based on my answer?” If not, tighten your structure.

This single habit, leading with a clear headline and framing your points, is the same communication style employed by every major consulting firm. 

Start practicing it now, and you will already sound like you belong in the room.

2. Build Slides That Make a Point

In consulting, slides are not just visuals. They are the product. 

Long before a final presentation, every workstream updates its findings through slides. 

A manager or partner will often skim your deck first before ever asking you to speak, and they will form an opinion of your thinking from those pages alone.

In a Bain training I once reviewed, they shared that a slide headline should read like a newspaper headline.

That’s clear enough that someone scanning quickly understands the point without needing to read the body text.

Now, what makes a slide effective?

The slide includes:

✔ A top-line headline that states the insight (not only the topics).
✔ Clean, minimal visuals (charts, tables) that support the insight.
✔ Logical flow from one slide to the next, building a narrative.

Here’s how you can start practicing now:

  • Take a business article, annual report, or even a case study. Instead of summarizing it in text, challenge yourself to summarize it in three slides.
  • Each slide should have a headline that states a conclusion (e.g., “Sales Growth Driven by Southeast Asia Expansion”) rather than a label (“Sales Data”).
  • Use simple visuals: one chart or table per slide.
  • Put the slides in order and ask yourself: “If I only read the headlines, do I understand the story?”

A quick example:

Weak headline: Q2 Sales Data
Strong headline: Q2 Sales Grew 15% Driven by Southeast Asia

Weak slide flow: Market trends scattered randomly
Strong slide flow:

  1. Market growth is slowing globally
  2. Southeast Asia remains the exception
  3. Expansion in that region drives overall sales

The idea is to pick a deck you admire (many consulting firms publish public reports) and reverse‑engineer it. Ask:

  • How do their headlines read?
  • How do they transition from one slide to the next?
  • What visuals do they use to make points clear?

If you start doing this now, by the time you join a project, you will not waste hours making slides that “look nice.” 

You will create slides that drive decisions. 

And that’s the kind managers remember and clients act upon.

3. Practice Hypothesis‑Driven Thinking

In consulting, you are not hired to just “find answers.” 

You are hired to lead thinking. 

That is why top consulting firms train their teams to use hypothesis‑driven thinking

A method where you start with a possible answer and test it, instead of exploring aimlessly.

Harvard Business Review explains this mindset in “Consulting Is More Than Giving Advice”.
Consultants create real value by working through problems with the client,  framing a point of view, testing it, and refining it together.

When you think this way, you save time, focus your research, and show to your team that you can frame a problem effectively.

Here’s how to build this skill now:

What to Do How to Practice
Start with a clear hunch Before diving in, say out loud: “My initial view is ___ because ___.”
Plan how to test it Ask yourself: “What evidence would prove or disprove this?” Write down 2–3 things you’d check.
Share your thinking early In group work, share your hunch and explain how you plan to test it, rather than waiting until the end.
Adjust quickly If the data says you’re wrong, refine your hunch and move on. That flexibility shows maturity.

Example:

Instead of saying:

“I need to look at everything to figure out why sales are down.”

Say this:

“I believe sales are down because repeat customers dropped. I’ll check the order data by customer type to confirm.”

This is how real consultants work every day.

It shows leadership in your thinking, and it is a skill you can start practicing right now, whether you’re in school, in your current job, or preparing for interviews.

4. Get Fast and Clean in Excel

In consulting, Excel is not “just a spreadsheet.” 

It is where most of the real analysis happens. 

No one has time to untangle a messy workbook. If your file is confusing, people stop trusting your work. 

Managers expect speed and logic. When they open your file, they want to see immediately how it works without you having to explain every step.

So, on real projects, deadlines are brutal. 

A client can request a new number an hour before a meeting, and you must comply. If your model is clunky, you lose that hour fixing instead of producing. 

The consultants who stand out are those who consistently deliver clean, reliable work every time.

Here’s how you can start now:

What to Do How to Practice
Focus on clarity, not complexity Build a simple budget, tracker, or model and ask: “Can someone else follow this?”
Use core functions well Practice with SUMIFS, VLOOKUP/XLOOKUP, pivot tables, and basic charts until they are second nature.
Keep workbooks clean Label sheets clearly, use consistent formatting, and avoid hidden steps.
Stress‑test your speed Time yourself: can you build a small model or pivot in 15 minutes? Then aim for 10.

Example drill:

Take your own expenses for the past three months.

  • Build a simple tracker in Excel.
  • Use a pivot table to group them by category.
  • Add a clean chart showing which category is highest.

Now hand it to someone else. If they can follow your steps and understand your chart in under a minute, you are on the right track.

In Module 2 of the High Bridge Consulting Readiness Program, we spend a lot of time sharpening exactly this. 

You can also start practicing this now, and you will already feel ahead when that first project hits your inbox.

5. Speak in Calm, Clear Sentences (Even Under Stress)

When pressure builds, the way you speak matters just as much as the work you deliver.

Consultants are trusted because they stay clear and steady even when things go sideways.

People remember how you handle tough moments.

If a deadline slips or numbers change last minute, you cannot sound frantic.
You need to sound in control. Clear, simple, and focused on solutions.

You can practice:

  • When a project or group task hits a snag, explain what happened without drama.
  • Skip filler words. Go straight to what matters and what happens next.
  • Maintain a level tone, even in stressful situations.

Example:

Instead of saying:

“We’re in trouble, everything’s delayed, and I don’t know what to do.”

Say this:

“The timeline shifted because a key input arrived late. Here’s how we can recover: step one, adjust X; step two, confirm Y.”

That calm clarity is exactly what hiring managers listen for when preparing for a case interview.

It shows you can think on your feet, and keep moving forward no matter what happen. 

Now, feeling calm under pressure? Good. 

Let’s keep that momentum and build habits that make it second nature.

Build Habits That Make You Interview‑Ready by Default

You’ve learned how to stay calm when it counts. Now let’s talk about the daily habits that turn good consultants into great ones.

1. Summarize Conversations Like a Consultant

After any meeting or class, take a minute to jot down a quick 3-line summary.

What was decided? What’s coming next, and who owns each action?

Doing this consistently sharpens your clarity. 

It helps you remember what matters, keeps your team aligned, and shows you’re someone who drives things forward. 

Sharing these summaries? 

That’s how you get noticed as the person who keeps projects on track.

2. Use “Workstream” Thinking on Your Own Projects

Think of every project as a small consulting engagement. 

Break it down into owners, deliverables, and blockers, even if you’re the only one doing the work.

This habit keeps you organized and proactive. Instead of juggling random tasks, you see the whole flow. 

It helps you identify where things can stall early, so you can fix problems before they escalate.

This way of thinking not only keeps you on top of your work but also demonstrates to interviewers that you can manage complexity and take charge without needing direction.

3. Do Weekly Reflections Like Post‑Mortems

Set aside about 10 minutes each week to check in with yourself and ask:

  • What worked well?
  • What didn’t go as planned?
  • What will I do differently next time?

The best consultants develop strong judgment by reflecting regularly on their wins and mistakes. 

Over time, this habit helps you make smarter decisions faster.

Try making it a routine. Pick a consistent time, maybe Friday afternoon or Sunday evening, and be honest with yourself. 

Write down your thoughts or just think them through.

This reflection habit turns everyday experiences into lessons. 

Get Comfortable With the Tools You’ll Use Every Day

Don’t wait until Day 1 to learn these tools. 

The more natural they feel now, the more mental space you save for real problem solving when the job starts.

Here are the key tools consultants use every day, and what to practice so you’re ready from the jump:

Tool What to Practice
PowerPoint Build decks with clear structure and strong headlines. Practice summarizing info in 3–5 slides.
Excel Master pivot tables, basic formulas like SUMIFS and VLOOKUP/XLOOKUP, and clean formatting. Build simple models others can follow.
Email Tools (e.g., Outlook) Manage your calendar with blocking, write clear emails, and follow up promptly.
Notion or OneNote Take quick notes, track actions, and create personal dashboards to keep yourself organized.
Google Docs Write clear, structured documents and learn to summarize fast for quick sharing.

Pro tip: When practicing, simulate real scenarios. For example, build a budget in Excel or draft an email follow-up for a project update. 

The goal is comfort. These tools should feel like an extension of your brain, not a hurdle.

Final Advice From Candidates Who Broke In

I’ve seen many people come through High Bridge Academy. Here’s what those candidates tell me helped them the most:

1. Act Like a Consultant Before You’re One 

Don’t wait for the job title to start thinking in structures, pushing for clarity, and taking ownership of your work. When you come to case interviews, already practicing this mindset, it shows. 

2. Make Slides Your Secret Weapon

Several candidates noted that practicing by turning case summaries or articles into decks on a weekly basis made the biggest difference. Again, when you build this muscle early, the dreaded “make me a deck by tomorrow” moment becomes just another task.

3. Build Reflection into Your Routine

Weekly self-reflection wasn’t just a nice-to-have. It helped sharpen pattern recognition and problem-solving instincts. That ability to look back, learn, and adjust is exactly what top consultants do on every project, and exactly what will set you apart in case interviews.

4. Treat Every Challenge Like a Consulting Problem

Whether it’s a school project, work task, or personal goal, apply consulting habits and communicate clearly. This way, you build your muscle memory for the real work ahead.

5. Prepare For Case Interviews by Practicing Under Pressure

Real candidates told us it’s not enough to know the frameworks. You need to cultivate a specific mindset: stay calm, structure your answers, lead with your hypothesis, and maintain a clear tone. 

The takeaway?

Breaking into consulting means being consistent, focused and prepared, combined with the right mindset. 

Start practicing these habits today, and when the offer comes, you’ll walk in ready.
