  "body_markdown": "## 1. Three-Minute Summary\n\nMost large Korean companies screen applicants with a standardized assessment known as the Korean-style aptitude test (인적성검사): a timed battery of verbal, numerical, and logical reasoning questions paired with a personality inventory. If your market uses similar assessments — SHL-style tests, cognitive ability screens — the preparation logic below transfers directly.\n\nIf this is your first time, today's to-do list has three items:\n\n1. Take one 20-minute mini mock test.\n2. Tag every wrong answer by type: verbal, numerical, data interpretation, logical reasoning, spatial, or situational judgment.\n3. Screenshot the official test guide for your target company — number of questions, time limit, whether wrong answers are penalized, and whether it's computer-based.\n\nThis is not a test you win by grinding volume. It's a test you win by **finding the question types you get wrong and shrinking them fast**.\n\n## 2. The Test at a Glance\n\n| Component | What it measures | Typical questions | How to prepare | Watch out for |\n|---|---|---|---|---|\n| Personality inventory | Disposition, organizational fit | Collaboration, conflict, rule compliance | Anchor answers to real episodes from your life | Don't role-play an idealized person |\n| Aptitude test | Reasoning, calculation, comprehension | Verbal, numerical, logic, spatial | Repeated practice by question type | Time-limit management |\n\nThe personality inventory is not about performing as an impressive person — it's about **answering similar questions by the same standard every time**.\n\n## 3. Strategy by Question Type\n\n| Type | Technique you can use immediately |\n|---|---|\n| Verbal reasoning | Read the answer choices before the passage and mark keywords |\n| Numerical / data interpretation | Before calculating, check units, ratios, and base years |\n| Logical reasoning | Convert conditions into symbols instead of reading them as prose |\n| Spatial reasoning | Track the rotation axis, the touching faces, and the folding direction |\n| Situational judgment | Judge in this order: company policy → customer impact → team collaboration |\n\nSamsung's GSAT is widely regarded as toughest in numerical and logical reasoning, while SK's SKCT is known for testing cognitive and execution competencies together. LG's assessment and Hyundai's HMAT-style tests can change their personality/aptitude mix and online format from one hiring cycle to the next — so always prepare against the official test guide in your target company's job posting.\n\n## 4. How to Diagnose Your First Mock Test\n\n1. Take one full test under timed conditions.\n2. Record your accuracy rate and average time for each question type.\n3. Pick only the two types with the lowest accuracy or slowest times as your priorities.\n4. Keep the remaining types warm with short daily practice.\n\nTrying to fix every question type from day one inflates study hours without moving your score.\n\n## 5. Study Plans by Available Time\n\n| Time available | Plan |\n|---|---|\n| 7 days | 2 past/mock tests, condensed error review, computer-based test (CBT) environment check |\n| 14 days | 5 days on core question types, 6 days on company-specific mock tests, 3 days of CBT practice |\n| 30 days | 10 days on fundamentals, 10 days on weak types, 7 days of full simulations, 3 days of final review |\n\nFor materials, use one general-purpose prep book to learn the question types, then switch to mock tests specific to your target company — that's the efficient order.\n\n## 6. The Time-Management Formula\n\nSet your per-question target time like this:\n\n`Target time per question = total time × 0.85 ÷ number of questions`\n\nThe remaining 15% is reserved for marking answers, reviewing, and handling questions you got stuck on.\n\nDuring the actual test, proceed in this order:\n\n1. On the first pass, solve only the easy questions.\n2. If you're stuck for more than 40 seconds, flag it and move on.\n3. If wrong answers are penalized, treat flagged items as candidates to leave blank.\n4. If there's no penalty, make a reasoned guess rather than leaving blanks.\n5. Spend the final 5 minutes only on flagged questions.\n\n## 7. Error-Log Template\n\n| Question | Type | Time spent | Why I got it wrong | Rule for next time |\n|---|---|---|---|---|\n| Data interpretation #12 | Ratios | 2 min 10 sec | Confused units (millions vs. hundreds of millions) | Circle the table title and units before calculating |\n\nKeep the log short. The point is to set, in one line, \"what I will do differently next time.\"\n\n## 8. Personality Inventory Consistency Sheet\n\nBefore the test, write down one real episode for each item below.\n\n| Item | My real episode |\n|---|---|\n| Collaboration |  |\n| Conflict |  |\n| Rule compliance |  |\n| Pressure situations |  |\n| Ethics |  |\n| Leadership |  |\n\nChoose extreme options only when they match how you actually behave. Pick \"always\" or \"never\" for image management, and you'll contradict yourself on the similar questions that appear later.\n\n## 9. Day-Before Checklist for Online/CBT Tests\n\n- Photo ID\n- Laptop power and charger\n- Backup internet or a mobile hotspot\n- Webcam and microphone working\n- The designated browser installed\n- Pop-up blockers disabled\n- A cleared desk\n- Confirmation of whether calculators or scratch notes are allowed\n- Login time added to your calendar\n- One mock test solved on the actual monitor you'll use\n\nFor online tests, your environment matters as much as your ability. The day before, don't cram new problems — practice solving on the real screen without interruptions.\n\n## 10. FAQ\n\n**Is guessing okay?**\nIf wrong answers are penalized, judge carefully. If the guide says there's no penalty, minimize blanks.\n\n**How long should I prepare?**\nTwo weeks as a baseline; four weeks is safer if numerical or logical reasoning is a weak spot.\n\n**Which prep book should I start with?**\nOne general-purpose book to learn the question types, then move to mock tests for your specific target company.\n\n**What's the very first thing to do?**\nScreenshot your target company's official test guide. If you don't know the question count, time limit, penalty policy, and whether it's computer-based, your study plan will point in the wrong direction.\n\n## Evidence and Scope\n\nThe 7-, 14-, and 30-day plans and the time-allocation formula are training heuristics, not statistical guarantees of a passing score. Adjust them after the first timed mock, and treat the current instructions from the employer as authoritative for format and scoring.\n\n- [SHL Candidate Support: Practice Tests and Assessment Advice](https://support.shl.com/category.html?c=10_91_12_54_55_&hl=en) — official candidate guidance on using practice material to learn an assessment format.\n- [Aon: Prepare for Your Assessment](https://assessment.aon.com/en-us/sites/site-map) — official candidate preparation resources and assessment categories.",
