ADHD and Consulting Case Interviews: How to Prepare

Consulting case interview preparation can feel especially demanding when you are trying to manage attention, structure your thinking, take clear notes, and keep pace at the same time. For candidates with ADHD, the most useful case interview preparation is not about assuming the same challenges apply to everyone. It is about identifying which parts of the process create friction for you and building practical systems around them. In this article, we will explore how to prepare for consulting case interviews with ADHD, including structuring, note-taking, pacing, calculations, practice routines, and when interview accommodations may be relevant.

TL;DR - What You Need to Know

Consulting case interview preparation for candidates with ADHD works best when practice methods are adapted to individual attention, structure, pacing, and communication needs.

• Clear page layouts help separate objectives, calculations, data, and insights during case interview note-taking.
• Attention management improves when candidates use visible objectives, brief pauses, and verbal signposting during the case.
• Structured calculation routines reduce avoidable errors by separating formulas, units, intermediate steps, and business interpretation.
• Case interview practice works best when focused skill drills are combined with realistic mock interviews and targeted review.
• Interview accommodations may be relevant when standard recruiting conditions create barriers, but policies and approval processes vary by firm.

How Should You Adapt Consulting Case Interview Preparation for ADHD?

Consulting case interview preparation for candidates with ADHD should be adapted around individual needs rather than assumed strengths or difficulties. Start by identifying where your performance becomes less consistent, such as structuring, listening, calculations, synthesis, or communication. Then adjust your practice methods to make those specific parts of the case easier to manage consistently.

ADHD does not affect every candidate in the same way. One person may find it harder to keep track of several pieces of information at once, while another may have no difficulty with that part of the interview.

For that reason, begin your case interview preparation by observing your own performance across several practice cases. Instead of asking whether ADHD makes case interviews harder overall, identify which specific moments create avoidable errors or require disproportionate effort.

A useful review can focus on five areas:

• Structuring: Can you turn an unfamiliar problem into a clear set of issues without losing track of the original objective?
• Listening: Can you capture the most important information while still following the interviewer?
• Calculations: Can you organize numbers, units, assumptions, and intermediate steps clearly?
• Synthesis: Can you pause, identify the main insight, and connect it back to the client's question?
• Communication: Can you explain your reasoning clearly without adding unnecessary detail?

After each mock case, note where performance started to decline. You might discover that your structure is strong but your notes become difficult to navigate later, or that your calculations are accurate but take longer when several numbers are introduced at once.

This kind of diagnosis makes consulting interview preparation more targeted. Instead of practicing complete cases repeatedly, you can spend additional time on the specific skill that is limiting your performance.

For example, if you regularly lose track of the case objective during exhibit analysis, write the objective at the top of every page and refer back to it before giving an insight. If you find transitions difficult, practice short verbal signposts such as stating what you have learned, what you want to examine next, and why.

You can also separate case interview practice into smaller skills before combining them again. Practice structuring independently, complete short mental math exercises, interpret individual charts, and rehearse concise recommendations.

The goal is not to create a completely different interview method. It is to build a repeatable system that reduces unnecessary cognitive load and allows you to demonstrate structured problem solving, active listening, hypothesis driven thinking, and clear case interview communication more consistently.

Your approach should also remain flexible. If a technique improves your performance during realistic mock interviews, keep it. If it adds complexity or distracts you from the conversation, simplify it or replace it.

How Can You Structure and Take Notes During a Case?

One of the most useful case interview tips is to keep your notes simple, consistent, and easy to scan. Separate the case objective, structure, data, calculations, and insights so you can retrieve information quickly without rereading full pages or trying to remember where you wrote something.

A consistent page layout can reduce unnecessary searching during the case. The goal is not to capture every word the interviewer says, but to record the information you are most likely to need later.

A practical setup can include:

• Objective: Write the client's main question at the top of the page.
• Structure: Keep your issue tree or case framework on a separate section or page.
• Data: Record only the figures, facts, and assumptions that are relevant to the analysis.
• Calculations: Show formulas, units, and intermediate steps clearly.
• Insights: Note the implication of each major finding, not just the number itself.

Avoid writing full sentences unless the wording is important. Short labels, abbreviations you understand, and simple visual spacing can make case interview note-taking easier to navigate.

For example, instead of writing, "Revenue decreased because customer volume fell significantly in the western region," you might write "West volume down -> revenue down." The shorter version preserves the insight while reducing the amount of writing required.

Keep calculations visually separate from descriptive notes. This helps prevent numbers from becoming mixed with qualitative information and makes it easier to check your work before communicating an answer.

It is also useful to leave some empty space on the page. Crowded notes can become difficult to scan as the case develops, especially when you need to connect a new exhibit or calculation to an earlier finding.

Your structure should remain visible throughout the discussion. When you finish one branch of the analysis, return to your original case interview structure and mark what has been addressed and what still needs to be tested.

You can also use a simple notation system for recurring information. For instance, use one symbol for assumptions, another for key insights, and a box around figures you expect to use again.

The best note-taking system is one you can use consistently under interview conditions. Practice the same layout during mock cases so that finding the objective, a calculation, or a previous insight becomes automatic rather than another task competing for your attention.

How Can You Manage Attention and Pacing During a Case?

Consulting case interview preparation can include simple attention and pacing systems that help you stay oriented throughout the discussion. Use the case objective as a reference point, pause briefly before major transitions, and communicate what you are analyzing next. The most useful approach is one that helps you maintain focus without interrupting your reasoning or communication.

Case interviews require you to listen, analyze, calculate, interpret information, and communicate your thinking in real time. Rather than trying to maintain perfect concentration throughout the entire case, create deliberate points where you can reorient yourself.

One useful technique is to keep the client objective visible at the top of your notes. Before moving into a new part of the analysis, quickly check whether the next question still helps answer that objective.

You can also use verbal signposting to make your reasoning easier to track. Short transitions can help both you and the interviewer understand where the analysis is going.

For example:

• "We have identified declining volume as the main revenue driver. I would next like to understand what is causing the volume decline."
• "This calculation suggests the opportunity is meaningful. I would now like to test whether it is operationally feasible."
• "Before moving on, I would like to summarize what we have learned so far."

These statements create natural checkpoints. They can help you organize your thinking without adding unnecessary detail to the conversation.

Pacing also matters. You do not need to respond immediately to every new question or exhibit.

When you receive a complex prompt, taking a brief pause to organize your thoughts can be more effective than beginning before you know how you want to structure the answer. You can tell the interviewer that you would like a moment to organize your approach before speaking.

For longer analytical tasks, break the work into clear stages:

• Confirm what question you are answering.
• Identify the information that matters.
• Complete one analytical step at a time.
• State the resulting insight.
• Connect that insight back to the case objective.

This approach can also help with attention management because you are focusing on one defined task rather than trying to process the entire case at once.

Avoid adding systems that create more work than they save. Multiple symbols, complicated timing rules, or detailed tracking methods may become another source of distraction if you have to consciously manage them during the interview.

Instead, test a small number of strategies during case interview practice. For example, you might experiment with keeping the objective visible, pausing before calculations, and summarizing after each major analysis.

Review whether each technique improves your accuracy, pacing, and communication. If it does, continue using it until it becomes familiar under realistic interview conditions.

The aim is not to eliminate every moment of distraction. It is to make it easier to recognize when your attention has shifted, return to the client question, and continue the case in a structured way.

How Can You Make Case Interview Calculations More Manageable?

Case interview preparation should include a consistent calculation process that makes quantitative work easier to follow and check. Write the equation before calculating, break larger problems into smaller steps, track units carefully, and communicate your logic as you work. This reduces avoidable errors and makes your reasoning easier for the interviewer to evaluate.

Case interview calculations are usually less about advanced mathematics and more about organizing information correctly. A clear process matters because even simple arithmetic can become harder when you are simultaneously listening, interpreting the business problem, and explaining your reasoning.

A practical calculation sequence is:

• Restate what you need to calculate.
• Write the formula before inserting numbers.
• Confirm the units for each input.
• Break the calculation into smaller steps.
• Write intermediate results clearly.
• Check whether the final number is reasonable.
• Explain what the result means for the case.

For example, if you need to estimate annual revenue from monthly customers and average spending, write the relationship first:

Revenue = Monthly customers x Average spending x 12

Then insert the numbers one step at a time rather than trying to solve the entire calculation mentally.

Keeping units visible is particularly useful. Write dollars, customers, percentages, millions, or other units next to each figure so that you do not accidentally combine numbers that are expressed differently.

You should also separate arithmetic from interpretation. First complete the calculation accurately, then ask what the result tells you about the client's problem.

For example, finding that a new product could generate $20 million in annual revenue is only the numerical result. The insight depends on context, such as the client's current revenue, investment required, profitability, and strategic objective.

If mental math creates unnecessary pressure, practice common consulting calculations in smaller components. These may include percentages, growth rates, weighted averages, breakeven calculations, market sizing, and basic profit equations.

Accuracy should come before unnecessary speed. Interviewers need to understand how you reached the answer, so a structured calculation with clearly stated assumptions is generally more useful than rushing through arithmetic without showing your reasoning.

When practicing, review the source of each mistake rather than recording only whether the answer was correct. A calculation error might come from arithmetic, copying a number incorrectly, missing a unit, choosing the wrong formula, or losing track of an intermediate result.

This distinction helps make case interview practice more targeted. If your arithmetic is accurate but your setup is inconsistent, more mental math drills alone will not address the real problem.

A repeatable calculation routine can reduce the amount of information you need to hold in your head at once. Over time, the sequence of setting up the equation, calculating in steps, checking the result, and stating the insight should become a familiar part of your case interview process.

How Should You Practice Case Interviews With ADHD?

Case interview practice for candidates with ADHD should combine focused skill drills with realistic full cases. Use practice sessions to identify where your performance becomes less consistent, then isolate that skill before returning to complete interviews. The goal is to build a repeatable preparation routine that improves accuracy, structure, pacing, and communication under realistic conditions.

Practicing more is not always the same as practicing better. If you complete full mock cases without reviewing what went wrong, you may repeat the same habits without improving the specific skill causing difficulty.

A more targeted practice routine can combine:

• Structuring drills for unfamiliar business problems.
• Short case interview mental math exercises.
• Exhibit interpretation using charts and tables.
• Synthesis practice after individual case sections.
• Full mock case interviews under realistic conditions.
• Post-case reviews focused on one or two improvement areas.

For example, if you consistently lose track of important information during longer cases, completing more full cases may not solve the problem by itself. You could instead practice listening to short prompts, taking concise notes, and summarizing the objective before moving into the analysis.

The same principle applies to calculations. If your arithmetic is accurate but you frequently copy numbers incorrectly, the most useful drill is not simply faster mental math. You should practice setting up calculations from exhibits and transferring figures carefully into your notes.

Keep practice sessions specific enough that you know what you are trying to improve. A session might focus only on building issue trees, interpreting exhibits, or delivering final recommendations.

You can then test that skill in a full case. This helps determine whether the technique still works when you are also listening, communicating, taking notes, and managing time.

It is also useful to make practice conditions progressively more realistic. Early sessions can allow additional time while you learn a process, but later mock interviews should resemble the format and pacing you expect in the actual interview.

After each practice case, review a small set of questions:

• Where did I lose track of the objective?
• Which part of the case required the most effort?
• Did my notes help me retrieve information quickly?
• Were calculation errors caused by arithmetic or by setup?
• Did I communicate insights clearly after each analysis?
• Which one or two changes should I test in the next case?

Avoid changing several elements of your approach at once. If you introduce a new note-taking system, pacing technique, and calculation process in the same session, it becomes difficult to tell which change actually helped.

A simple practice log can make progress easier to evaluate. Record the type of case, the skill you were testing, recurring mistakes, and the adjustment you want to try next.

The most effective routine is the one that produces consistent improvement in realistic mock cases. Your case interview practice should therefore become increasingly personalized as you learn which structures, habits, and preparation methods help you perform most reliably.

When Should You Consider Interview Accommodations?

You may want to consider interview accommodations if a disability or health related need affects your ability to participate in the standard recruiting process. Accommodation policies vary by firm, assessment, location, and individual circumstances, so review the employer's current guidance and contact the recruiting team early if you believe an adjustment may be relevant.

Requesting an accommodation is different from changing your case interview preparation strategy. Preparation techniques are personal methods you use to improve performance, while accommodations are formal adjustments approved through an employer's recruiting process.

For example, McKinsey states that candidates with disabilities can request accommodations during the recruiting process. Its current assessment guidance also notes that exceptions to standard assessment rules may apply when an accommodation has been formally approved.

BCG similarly states that candidates who need reasonable accommodations during the interview process should inform their recruiter as soon as possible.

If you think accommodations may be relevant, a practical process is:

• Review the firm's official recruiting and accessibility information.
• Contact the recruiter or designated accommodations team early.
• Ask what adjustments may be available for the specific interview or assessment.
• Follow the firm's process for providing any required information.
• Confirm which accommodations have been approved before the interview.
• Ask whether the approved adjustment applies to every stage of the recruiting process.

Do not assume that an accommodation used at university, work, or another employer will automatically apply in the same form. Firms may have their own procedures, and the appropriate adjustment depends on the recruiting activity and individual circumstances.

You also do not need to decide what an accommodation should look like based solely on general ADHD advice. If you believe an adjustment is necessary, the recruiting or accessibility team can explain the firm's process and what information it requires.

Timing can matter. Contacting the firm before an assessment or interview gives the recruiting team an opportunity to review the request and explain any next steps rather than trying to address the issue immediately before the interview.

McKinsey's current guidance, for example, directs candidates who need special arrangements or accommodations during the interview process to its accessibility process and recruiting contacts.

Accommodation policies can change, so verify current information directly with the firm rather than relying on older candidate experiences or unofficial sources. This is particularly important for online assessments, where standard rules about timing, note-taking, technology, and permitted tools may differ when an accommodation has been formally approved.

The purpose of this section is not to determine whether you need an accommodation. That decision depends on your circumstances and the firm's process. The practical step is to understand your own needs, review the current policy, and communicate with recruiting early enough to understand what options are available.
