Is it better to accept "I don't know" vs making up answers in IIM interviews?

Absolutely better to accept "I don't know" than make up answers in IIM interviews because panels are trained to detect bluffing through follow-up questioning, and exposed bluffing is the fastest way to fail. Panels can tolerate gaps in knowledge (everyone has them) but not intellectual dishonesty. Framework for unknown questions:

1. Pause briefly to organize thoughts.

1. Acknowledge the gap: "Sir/Madam, I am not aware of this specific topic."

1. Offer adjacent knowledge if possible: "I know related area X" or "I can reason from general principles."

1. Commit to post-interview research: "I will look into this after the interview."

1. Move forward with composure. Weak responses:

1. Bluffing with made-up facts (easily exposed in follow-up).

1. Extensive apologies for not knowing.

1. Changing topic abruptly.

1. Blaming knowledge gap on external factors. The "I don't know, but I'll learn" response demonstrates:

1. Self-awareness,

1. Intellectual honesty,

1. Growth mindset,

1. Respect for interviewer's time. Panels at IIM A, B, C explicitly value these traits because MBA students face daily unknown situations (case discussions, client problems, exam topics not covered in class). Comfortable acknowledgment of limits is leadership quality. However, do not over-use "I don't know". If you say it 5+ times in 20-minute interview, panels conclude you lack preparation depth. Aim for maximum 2-3 unknown acknowledgments in an interview. For known topics, answer with structured confidence. For unknown, acknowledge briefly and pivot to related knowledge. Example: Question "What is India's current forex reserves?" If you don't remember exact figure: "Sir, I don't remember the exact current figure but I know it has been fluctuating around $600-650 billion range in past year based on RBI interventions to stabilize rupee. I can speak to the general trend and drivers if useful." This acknowledges limit while demonstrating adjacent knowledge. Panels appreciate the structure. For questions completely outside your domain: "I am not familiar with this topic. Could you help me understand briefly and I'll attempt to reason?" Panels often adjust questions when candidates signal honest limits. IIM A at Rs 27.5L fees for Rs 35.22 LPA avg admits candidates who handle uncertainty gracefully.
