class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Key Takeaways<\/h2>\n\n\n\n<ul>\n<li>Most candidates fail due to structure and communication gaps<\/li>\n\n\n\n<li>Jumping to solutions is the most frequent mistake<\/li>\n\n\n\n<li>Weak hypothesis-driven thinking reduces clarity<\/li>\n\n\n\n<li>Structured feedback accelerates improvement<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Mistake 1: Jumping Straight to the Solution<\/h2>\n\n\n\n<p>Many candidates immediately suggest answers after hearing the problem.<\/p>\n\n\n\n<ul>\n<li>In consulting \u2192 signals weak structure<\/li>\n\n\n\n<li>In product \u2192 shows lack of user understanding<\/li>\n<\/ul>\n\n\n\n<p>Instead:<\/p>\n\n\n\n<ul>\n<li>Clarify the objective<\/li>\n\n\n\n<li>Define assumptions<\/li>\n\n\n\n<li>Structure the problem<\/li>\n\n\n\n<li>Then proceed<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Mistake 2: Not Defining the Objective Clearly<\/h2>\n\n\n\n<p>Failing to clarify:<\/p>\n\n\n\n<ul>\n<li>Revenue vs profit<\/li>\n\n\n\n<li>Short-term vs long-term<\/li>\n\n\n\n<li>Growth vs retention<\/li>\n\n\n\n<li>Cost vs expansion<\/li>\n<\/ul>\n\n\n\n<p>Leads to

class=\"wp-block-heading\">Mistake 3: Weak Hypothesis-Driven Thinking<\/h2>\n\n\n\n<p>Without hypotheses:<\/p>\n\n\n\n<ul>\n<li>Analysis becomes random<\/li>\n\n\n\n<li>Exploration lacks direction<\/li>\n\n\n\n<li>Answers feel scattered<\/li>\n<\/ul>\n\n\n\n<p>Building this skill is critical, and a deeper approach is explained in <a

class=\"wp-block-heading\">Mistake 6: Memorizing Frameworks Instead of Thinking<\/h2>\n\n\n\n<p>Over-memorization leads to:<\/p>\n\n\n\n<ul>\n<li>Rigid structures<\/li>\n\n\n\n<li>Forced frameworks<\/li>\n\n\n\n<li>Misfit approaches<\/li>\n<\/ul>\n\n\n\n<p>Interviewers easily detect memorized thinking.<\/p>\n\n\n\n<hr class=\"wp-block-separator
