CaseInterview.com and Victor Cheng

What Is CaseInterview.com?

CaseInterview.com is a founder-led educational resource built around Cheng’s explanations of consulting recruiting and case problem-solving. His background includes consulting, resume screening, and case interviewing at McKinsey. That experience provides context for his teaching, particularly its attention to how an interviewer may interpret a candidate’s reasoning and communication.

A recurring element of the approach is hypothesis-driven analysis: forming a tentative explanation, identifying what evidence would test it, and revising the explanation as information emerges. Cheng uses issue trees—diagrams that divide a problem into smaller questions—to organize this process. His guidance emphasizes adapting the structure to the case rather than treating memorized frameworks as universal answers.

Consulting preparation is the website’s central subject, although it also publishes broader material on networking, career development, and workplace skills.

What Does CaseInterview.com Help Candidates Prepare For?

Case Interviews and Structured Problem-Solving

The case materials address clarifying the problem, organizing an analysis, asking for relevant information, interpreting findings, and presenting a supported recommendation. Teaching examples include profitability, market entry, growth, acquisitions, and capacity decisions. The emphasis is on explaining the reasoning behind an answer, not simply reaching a numerical result.

The website also provides material on estimation and market-sizing questions, giving candidates additional ways to practice breaking an ambiguous question into manageable assumptions and calculations.

Case Math and Business Interpretation

Quantitative resources cover both computation and the business meaning of calculations. Topics include arithmetic, percentages, market share, revenue, and profit. Separate mental-math instruction addresses simplifying calculations and deciding when an approximation is appropriate, while the interactive practice tool provides precise-calculation and estimation exercises.

Personal Experience and Behavioral Interviews

Cheng’s personal experience interview material addresses the non-case discussion of a candidate’s experiences and interpersonal capabilities. Its delivery combines written guidance, video instruction, and example storytelling material. This is a distinct preparation area rather than an assumed outcome of studying cases.

Applications and Networking

Application resources include resume and cover-letter instruction, examples, and commentary. Resume materials illustrate evaluation and rewriting decisions; networking guidance addresses approaching people and developing conversations that may support the application process. These resources concern obtaining an interview, rather than performing in the interview itself.

How CaseInterview.com Works

The principal delivery model is self-directed learning. Candidates read articles or the book, watch instruction, work through supporting materials, and select additional resources around particular preparation needs. Some online learning materials are accessed through registration, with email guidance accompanying the preparation resources.

Look Over My Shoulder, often abbreviated to LOMS, uses audio recordings of candidates working through cases, accompanied by Cheng’s commentary and transcripts. Candidates hear contrasting approaches and explanations of what worked or went wrong. The recordings include both candidate-led and interviewer-led case formats; their central learning activity is examining the problem-solving conversation.

Cheng’s instructions for using these recordings favor active participation. He suggests pausing to identify a mistake, anticipate his commentary, or restate an answer before continuing. This makes the exercise a form of guided analysis rather than simply listening to completed solutions.

Who May Find CaseInterview.com Useful?

Based on the formats and subjects covered, CaseInterview.com may be relevant to several candidate situations:

• Learning cases for the first time: Candidates seeking explanations of the case process before moving into extensive interview practice.
• Connecting business concepts with calculations: Candidates who can perform arithmetic but want to understand what a result means for a business decision.
• Examining recurring mistakes: Candidates who know the basic concepts but want to study how inefficient questioning or incomplete analysis develops during a case.
• Preparing before interview invitations: Applicants seeking self-study guidance on resumes, cover letters, and networking alongside eventual case preparation.

How CaseInterview.com Can Fit Into Consulting Interview Preparation

A practical way to organize these materials is to assign each format a specific purpose rather than working through every resource indiscriminately:

• Establish the fundamentals. Use introductory instruction to understand how to clarify, analyze, and close a case. Practice explaining those steps in plain language.
• Study decision-making in context. Use recorded examples to examine why a candidate chose a question or analytical direction, then compare that choice with the commentary.
• Separate calculation practice from business reasoning. Work on arithmetic through drills, while using the math instruction to examine which calculation is relevant and how to interpret it.
• Move into live practice. Apply the concepts with another person who can question an assumption, interrupt an explanation, or ask for clarification. Cheng’s own guidance distinguishes understanding a technique from performing it in an interactive interview.
• Prepare the non-case components separately. Allocate time to application materials and personal experience stories rather than allowing case work to displace them.

Official firm resources can serve a different purpose: confirming expectations and supplying practice examples directly from the recruiting organization. Candidates can combine those materials with self-study and peer practice without treating any particular commercial resource as a prerequisite.

What to Consider When Using CaseInterview.com

• Recorded feedback is not individualized feedback. LOMS commentary concerns the candidates in its recordings. Consider how personal performance will be assessed separately, especially communication under questioning.
• Frameworks require adaptation. Cheng explicitly discusses changing an issue tree when new evidence reveals that the original structure is unsuitable. Use the materials to understand that adjustment, not merely to reproduce a diagram.
• Different resources address different needs. Case instruction, math practice, personal experience preparation, and application guidance are distinct components. Check the scope of the particular resource rather than assuming one book or course covers every recruiting stage.
• Founder experience and firm requirements are different things. Cheng’s former interviewing role explains his perspective; it should not be treated as a statement of every firm’s recruiting requirements. Confirm interview details through the hiring firm.

Frequently Asked Questions About CaseInterview.com and Victor Cheng

Who is Victor Cheng?

Victor Cheng is the founder of CaseInterview.com and author of Case Interview Secrets. His professional background includes work as a McKinsey consultant, resume screener, and case interviewer.

How are CaseInterview.com and Case Interview Secrets related?

Case Interview Secrets is Cheng’s book on case interview preparation. CaseInterview.com is the broader website through which readers encounter his articles, preparation programs, and related recruiting resources.

What is Look Over My Shoulder?

LOMS is an audio-based case preparation program with transcripts and Cheng’s commentary. It lets candidates examine different performances and the reasoning behind his assessment of them.

Is the preparation only for McKinsey applicants?

No. The recorded case materials address interviewer-led and candidate-led formats and include examples described as McKinsey-style and Bain- or BCG-style preparation.

Does CaseInterview.com cover fit or behavioral interviews?

Its personal experience interview materials address presenting relevant experiences and preparing personal stories. Candidates should distinguish that material from the analytical case resources when planning their preparation.

Can candidates use the resources without a practice partner?

Yes. Reading, video instruction, math exercises, and analysis of recorded interviews can be undertaken independently. Cheng also advocates live practice to apply those lessons while responding to another person.
