Is 30 days enough for case interview preparation?<\/strong><\/h6>\n\n\n\n<p>It can create meaningful improvement when practice is focused and reviewed. Candidates starting from different baselines may need more or less time.<\/p>\n\n\n\n<h6 class=\"wp-block-heading\"><strong>2. How many cases should I practise in 30 days?<\/strong><\/h6>\n\n\n\n<p>There is no universal number. Prioritize reviewed cases, targeted drills and repeated weak sections over a high count without learning.<\/p>\n\n\n\n<h6 class=\"wp-block-heading\"><strong>3. Should I prepare differently for product and consulting roles?<\/strong><\/h6>\n\n\n\n<p>Yes. Both require structure and communication, but product cases place more emphasis on users, metrics and product judgment, while consulting cases often emphasize business diagnosis and quantitative analysis.<\/p>\n\n\n\n<h6 class=\"wp-block-heading\"><strong>4. Should I practise alone or with a partner?<\/strong><\/h6>\n\n\n\n<p>Use both. Solo drills build specific skills, while partner practice develops live clarification, adaptability and communication.<\/p>\n\n\n\n<h6 class=\"wp-block-heading\"><strong>5. What should I do during the final week?<\/strong><\/h6>\n\n\n\n<p>Run timed mocks, review recurring errors, repeat weak sections and reduce new learning.
