Most candidates benefit from enough practice to become consistent, not from chasing a fixed number. Focus on quality, review, and covering a range of case types.

Start with profit equals revenue minus costs, then tailor each branch to the business. The best structure is specific enough to guide analysis without becoming a memorized checklist.

Build reliable written steps before trying to calculate faster. Daily drills help, but most gains come from clearer setup, sensible rounding, and checking whether the result makes business sense.

Preparation and application timing should be planned together. Do not wait for perfection, but make sure you understand the recruiting calendar and can reach interview readiness before interviews are likely to begin.

Consulting resumes are about evidence of impact, leadership, problem solving, and achievement—not prior consulting job titles. Translate your strongest experiences into concise, quantified bullets.

Ask focused questions that draw on the person's actual experience and help you understand the firm, office, or role. Avoid questions that can be answered from the firm's website.

The McKinsey Personal Experience Interview goes deeper on a small number of stories. Expect detailed follow-up questions about your actions, thinking, interactions, and results.

Practice structured case thinking in a timed digital format. You still need sound business judgment, clear math, and careful reading even though the interaction differs from a live interview.
