Prepmatter: Consulting Interview Preparation

What Is Prepmatter?

Prepmatter focuses primarily on candidates pursuing management consulting roles, including positions at McKinsey, BCG, Bain, and other consulting firms. Its interview materials address both analytical problem-solving in cases and the presentation of a candidate’s experience and motivation in fit interviews.

The business was founded by former BCG consultants and provides its own educational content alongside coaching. It is therefore broader than a service for finding an interview coach. Although consulting is its central focus, its application course also addresses resumes, cover letters, and networking for professions such as investment banking and technology.

What Does Prepmatter Help Candidates Prepare For?

Case Interviews and Analytical Skills

The case curriculum covers clarifying a business problem, building a structure, market sizing, financial analysis, note-taking, and delivering a conclusion. It introduces candidate-led and interviewer-led cases, with examples across business situations such as profitability, pricing, market entry, growth, investment, and operations.

Targeted exercises address framework development, structuring, exhibit interpretation, mental math, and business calculations. These provide a way to practice individual components separately from a complete case. The mental-math resource distinguishes between precise calculation and estimation, with exercises involving basic arithmetic and financial concepts.

Fit, Behavioral, and Personal Experience Interviews

Fit preparation includes lessons and recorded examples addressing personal introductions, motivation for consulting, interest in a firm, and experience-based questions. The curriculum includes McKinsey’s Personal Experience Interview, or PEI, alongside examples involving influence, conflict, and other workplace situations. Candidates can also prepare questions to ask an interviewer.

Applications and Networking

Prepmatter’s application materials combine instructional videos, document templates, sample resumes and cover letters, and networking guidance. A separate application-review service provides personalized feedback on document content, structure, and formatting, including how accomplishments and motivation are presented. This distinguishes general instruction from feedback on a candidate’s own materials.

Consulting Online Assessments

Assessment preparation includes simulations for McKinsey Solve, practice for the BCG Online Case and Consulting Career Assessment, and Bain-focused SOVA and TestGorilla resources. Depending on the resource, practice involves interactive scenarios, timed reasoning questions, explanations, or performance feedback.

These resources are preparation products, not the assessments administered by consulting firms. Prepmatter explicitly describes its BCG Consulting Career Assessment and Bain TestGorilla materials as independently developed rather than official or endorsed products.

How Prepmatter Works

Candidates interact with Prepmatter through several distinct formats:

• Self-directed learning: Recorded instruction and interview examples introduce concepts, while templates, full cases, and drills provide opportunities to apply them. The interview course is delivered online and can be studied independently.
• Peer practice: Candidates request or join meetings with other applicants, exchange case or fit interviews, and provide feedback. The platform supports scheduling, language preferences, and tracking feedback from practice meetings. Participants take turns acting as interviewer and interviewee.
• Individual coaching: Candidates select a named coach and work on priorities such as case performance, fit answers, networking, or application strategy. Coaching is conducted remotely and is described as tailored to the candidate’s needs.
• Assessment practice: Candidates work through the relevant simulation or practice tests and review the associated explanations or feedback. This is a separate activity from conducting a live mock case interview.

Who May Find Prepmatter Useful?

The available formats suggest several use cases. Candidates learning cases for the first time may find the sequence of lessons and examples relevant. Those already completing full cases may instead focus on specific exercises in structuring, exhibit interpretation, or calculations. The interview course addresses undergraduate, MBA, and experienced-professional applicants.

Candidates without a regular practice partner may use the peer network, while those seeking individual feedback may consider coaching. Applicants working toward an application rather than an imminent interview may focus on document preparation and networking. These are different uses of the platform, not a requirement to work through every resource.

How Prepmatter Can Fit Into Consulting Interview Preparation

A preparation plan can assign different roles to Prepmatter’s instructional material, exercises, and live practice. One possible sequence is:

• Develop application documents: Draft the resume and cover letter before requesting personalized review, so feedback can address substantive choices rather than an unfinished outline.
• Learn case fundamentals: Study problem clarification, structuring, analysis, and synthesis before expecting to manage all these activities in a live case.
• Use drills between full cases: Select exercises that address observed weaknesses rather than treating completion of the entire library as the objective.
• Apply learning through conversation: Use peer interviews or coaching to practice explaining reasoning aloud and responding to questions. Review feedback before deciding what to practice next.
• Prepare experience examples alongside cases: Build answers around genuine experiences, personal actions, and outcomes rather than reproducing sample responses.

Assessment preparation can sit alongside this sequence when relevant to a recruiting invitation. Official firm guidance and sample cases provide another reference point; a commercial preparation resource need not be the starting point for every candidate.

What to Consider When Using Prepmatter

• Resource scope: Check which learning materials and services are included in the access being considered. Prepmatter presents courses, assessment preparation, application review, and coaching as distinct offerings; do not assume one enrollment includes every service.
• Coach selection: Review the individual coach’s background and approach, and agree on the purpose of the session. The platform itself encourages candidates to examine coach profiles rather than treating coaches as interchangeable.
• Source of feedback: Peer meetings involve feedback from fellow candidates. Consider which observations are specific and actionable, and which may need further discussion or a second perspective.
• Assessment relevance: Match any preparation product to the assessment named in the recruiting invitation. Treat simulation feedback as study guidance, not as an official score or forecast of a hiring decision.

Frequently Asked Questions About Prepmatter

Does Prepmatter focus exclusively on consulting?

Consulting recruiting is its primary focus. Its application course also addresses candidates pursuing investment banking, technology, and other industry roles, particularly through resume, cover-letter, and networking instruction.

Both. Candidates can use instructional content and exercises independently, arrange peer interviews, or work individually with a coach. These formats serve different preparation needs.

Does Prepmatter cover McKinsey’s PEI?

Yes. The fit-interview curriculum includes dedicated PEI material, and Prepmatter identifies PEI preparation as an area that can be addressed through coaching.

Can candidates find case-practice partners through Prepmatter?

Yes. Its peer-practice platform allows candidates to request or join meetings for case and fit practice. Participants exchange interviewer and interviewee roles and can submit feedback afterward.

Can Prepmatter review a candidate’s resume or cover letter?

Yes. Its application-review service provides personalized document feedback, including suggested revisions to content, structure, and formatting. This is separate from studying the general application course and templates.

Are Prepmatter’s assessment simulations official consulting-firm tests?

No. They are preparation resources. Its BCG Consulting Career Assessment and Bain TestGorilla disclaimers explicitly distinguish the practice materials from official products and state that the relevant firms do not endorse them.
