- Accuracy is more important in case interviews. Interviewers would rather allow more time for candidates to perform calculations correctly than to have a quick but incorrect answer.
- A balanced approach should be aimed for in entrance tests (McKinsey PST or BCG Potential Test). As the time allowance in those tests is very tight, slowing down to get accurate answers may not be the best approach.
- Case Interview Prep: Divide your practice into small hurdles, 5 or 10 questions each. Target 100% accuracy. Any score less than 100% is considered as failed. When you can consistently pass hurdles, try to reduce the time. You may practice calculating out loud as if you are presenting your calculation to interviewers.
- Entrance Test Prep (McKinsey PST or BCG Potential Test): Divide your practice into smaller hurdles, 5 or 10 questions each. Only allow yourself 30 – 45 seconds per question (start with 45 and then gradually move down to 30). Then try to increase the number of correct answers within the pre-targeted time allowed.
