# Why You Choke in Interviews (And the Science-Backed Fix)
A post on r/Indian_Academia recently captured a frustration that thousands of MBA candidates experience every year.
"I gave CAT this year and got 89 percentile. During prep, I had solved 40+ mocks and was usually scoring in the 70-80 range. But on the actual exam day I completely messed up. Extreme anxiety, slept only 2 hours, panicked the whole day, did not follow any strategy and everything went downhill."
The candidate added: "I genuinely feel I can do much better than this, at least 95 percentile, if I handle my anxiety better."
This is not an isolated case. Across Reddit forums, coaching center discussion boards, and candidate WhatsApp groups, the same pattern emerges. Candidates who perform excellently in practice sessions completely fall apart when the stakes become real.
The phenomenon has a name in performance psychology: choking under pressure. And understanding the science behind it is the first step toward conquering it.
The Neuroscience of Choking: Why Your Brain Betrays You
When you sit down for a mock interview with a friend, your brain operates in a relaxed, fluid state. Information flows easily. Responses come naturally. You feel competent and confident.
But when you walk into an actual IIM interview room, something changes. Your brain perceives the high-stakes situation as a threat, triggering what neuroscientists call the stress response system. Cortisol and adrenaline flood your system. Your prefrontal cortex, the region responsible for complex reasoning and working memory, begins to malfunction.
Research by Dr. Sian Beilock at the University of Chicago, published in the Journal of Experimental Psychology, demonstrates that pressure hijacks the very cognitive resources you need to perform well. The working memory that stores your prepared answers, retrieves relevant examples, and structures coherent responses becomes compromised.
The cruel irony is that the more you care about performing well, the more likely you are to choke. Studies on expert performance show that even highly skilled individuals experience dramatic performance drops when they become overly conscious of their movements or thoughts.
This explains why your mock interview performance does not predict your actual interview performance. The practice environment lacks the threat signals that trigger choking.
The Three Types of Interview Chokers
After coaching over 500 candidates through GDPI rounds, I have observed three distinct patterns of choking behavior. Understanding which category you fall into helps target the right interventions.
Type 1: The Overthinker
These candidates know their material cold. They have prepared extensively. But in the interview room, they begin second-guessing every response. Should I have said that differently? Was that example strong enough? Are they judging me negatively?
This constant self-monitoring consumes cognitive resources that should be devoted to actually answering questions. The result is halting responses, excessive qualifiers, and answers that trail off without clear conclusions.
Reddit Signal: "I know all the answers but my mind goes blank when I try to articulate them under pressure."
Type 2: The Physiological Reactor
For these candidates, the body takes over. Racing heart. Sweaty palms. Shallow breathing. Dry mouth. The physical symptoms of anxiety become so overwhelming that cognitive function becomes secondary.
Some candidates report feeling like they are watching themselves from outside their body. Others describe tunnel vision where they can only focus on the panelists' expressions rather than the questions being asked.
Reddit Signal: "I slept only 2 hours before my interview. I was shaking so much I could barely sit still."
Type 3: The Perfectionist Paralyzed
These candidates set impossibly high standards for their interview performance. Every question must have a perfect answer. Every response must impress the panel. This perfectionism creates a kind of paralysis where anything less than ideal feels like failure.
When they inevitably produce a response that does not meet their internal standard, they spiral. One imperfect answer leads to rumination about that answer, which leads to poor performance on subsequent questions.
Reddit Signal: "I know I could have done better. I keep replaying my answers and thinking about what I should have said."
Why Traditional Interview Prep Fails
The standard approach to interview preparation involves content mastery. Learn about the school. Prepare your introduction. Practice common questions. Know your resume inside out.
This approach addresses the knowledge component of interview performance while completely ignoring the performance component.
Research on skill acquisition by Anders Ericsson distinguishes between declarative knowledge (knowing what to say) and procedural knowledge (being able to say it under pressure). Most candidates prepare declarative knowledge extensively while neglecting procedural knowledge entirely.
This is why candidates perform well in low-stakes practice and poorly in high-stakes reality. They have the knowledge but lack the performance skill.
The Mock Interview Problem
Traditional mock interviews help, but they have significant limitations.
Limited Volume: Most candidates do 5-10 mock interviews before their actual panel. This is insufficient to develop automatic responses that do not require conscious monitoring.
Insufficient Stress: Mock interviews with friends, family, or even coaching center instructors rarely replicate the genuine threat signals of actual high-stakes interviews. Your brain knows the stakes are not real.
Delayed Feedback: When feedback comes hours or days after practice, the specific moments that need improvement have faded from memory. Immediate feedback loops are essential for skill acquisition.
Inconsistent Quality: Human mock interviewers tire, have off days, and cannot maintain consistent pressure across dozens of sessions.
The Science-Backed Fix: Stress Inoculation Training
The solution comes from an unexpected source: military and law enforcement training. Organizations that need people to perform complex tasks under extreme stress have developed a methodology called Stress Inoculation Training (SIT).
The core principle is simple but counterintuitive: you cannot eliminate anxiety, but you can train your brain to perform despite anxiety. This requires deliberate exposure to stress conditions during practice.
Component 1: Education
Understanding why choking happens reduces its power. When you recognize the physiological symptoms of stress as normal rather than signs of impending failure, you can observe them without being overwhelmed by them.
The racing heart is not evidence that you are failing. It is evidence that your body is preparing for a challenge. Research on stress reappraisal shows that viewing stress responses as helpful rather than harmful actually improves performance.
Component 2: Skill Acquisition Under Pressure
Practice sessions must include genuine pressure elements. This means:
Time Pressure: Responses must come within realistic time constraints. Unlimited time to formulate perfect answers does not prepare you for real interview pacing.
Interruption Training: Panelists interrupt. They challenge your statements. They express skepticism. Practice must include these disruptions rather than polite listening.
Failure Recovery: The ability to recover after a poor response is a learnable skill. Practice sessions should include deliberately difficult questions followed by opportunities to recover composure.
Volume: Deliberate practice research indicates that 50+ focused practice sessions yield significantly better results than 5-10 sessions. Most candidates under-practice by a factor of five to ten.
Component 3: Arousal Control Techniques
Specific techniques can regulate physiological stress responses in real-time.
Tactical Breathing (Box Breathing): Inhale for 4 counts, hold for 4 counts, exhale for 4 counts, hold for 4 counts. This technique, used by Navy SEALs, activates the parasympathetic nervous system and reduces cortisol levels within seconds. Practice this before entering the interview room and use it between questions.
Grounding: When anxiety causes dissociation, physical grounding brings you back. Press your feet firmly into the floor. Feel the chair supporting you. These physical anchors prevent the floating, disconnected feeling that accompanies severe anxiety.
Pre-Performance Routines: Athletes develop consistent pre-shot routines that trigger focused states. Develop a pre-interview routine: specific breakfast, specific clothing, specific arrival timing, specific mental preparation in the waiting room.
The 72-Hour Protocol: Preparing for High-Stakes Performance
The 72 hours before your interview determine more about your performance than the previous months of content preparation. Most candidates spend this time cramming additional information, which actually increases cognitive load and anxiety.
72 Hours Before
Stop learning new information. Your job now is consolidation, not acquisition. Review key frameworks and personal stories, but do not add new material.
Begin sleep optimization. Shift your sleep schedule if necessary so that interview day falls during your natural alertness peak. Avoid screens for two hours before sleep.
48 Hours Before
Conduct a full-length mock interview under realistic conditions. This is your final stress inoculation session. After this, no more practice. You are ready or you are not.
Prepare all logistics: clothing laid out, documents organized, route confirmed. Eliminate every possible source of day-of-stress.
24 Hours Before
Light physical activity only. A walk or gentle stretching releases nervous energy without depleting you.
Visualization: spend 20 minutes mentally rehearsing successful interview performance. Research on mental practice shows that vivid visualization activates the same neural pathways as actual performance.
No cramming. No last-minute preparation. Trust your training.
Day Of
Wake early enough to eliminate rushing. Follow your established routine exactly.
Arrive early but not excessively early. Waiting too long in the interview venue increases anticipatory anxiety. 15-20 minutes before is optimal.
Use tactical breathing in the waiting room. Observe your anxiety without judging it. Remember: the stress response is your body preparing for a challenge, not predicting failure.
What to Do When You Start Choking Mid-Interview
Despite optimal preparation, you may feel anxiety symptoms emerging during your interview. Here is the in-the-moment protocol.
The Pause
You are allowed to pause before answering. A deliberate pause of 3-5 seconds does not signal weakness. It signals thoughtfulness. Use this pause to take one deep breath and collect your thoughts.
The Reset Phrase
Prepare a phrase that allows you to restart an answer that has gone off track: "Let me put that more clearly..." or "Actually, let me reframe that..." These phrases give you permission to recover from a stumble without pretending it did not happen.
The Grounding Check
If you feel dissociation beginning, press your feet into the floor. Feel the texture of your clothing. These physical sensations anchor you in the present moment rather than spiraling into worry about how you are being perceived.
The Single Question Focus
Anxiety often comes from thinking about the entire interview rather than the current question. Deliberately narrow your focus to only the question in front of you. The next question does not exist yet. The previous question is over.
School-Specific Anxiety Patterns
Different IIM interview styles trigger different anxiety patterns.
[IIM Ahmedabad](/schools/iim-ahmedabad): The Intellectual Intensity Pattern
IIM-A interviews probe deeply into your thinking. The anxiety pattern involves fear of appearing unintelligent when panelists challenge your statements.
Counterbalance: Recognize that IIM-A panelists expect to challenge you. Being challenged is not a sign of failure. Prepare to say "I had not considered that perspective" without shame.
[IIM Bangalore](/schools/iim-bangalore): The Silence Pattern
IIM-B interviews sometimes include extended silences or minimal acknowledgment of responses. Candidates interpret silence as disapproval.
Counterbalance: Silence is not negative feedback. It is the panelists thinking. Do not fill silence with anxious additions to completed answers.
[IIM Calcutta](/schools/iim-calcutta): The Rapid-Fire Pattern
IIM-C panels sometimes move quickly through questions. The anxiety pattern involves feeling rushed and not having time to formulate complete answers.
Counterbalance: You set your own pace. Taking a breath before responding is more impressive than stumbling through rapid responses.
The Volume Imperative: Why Most Candidates Under-Prepare
The Reddit data reveals a consistent pattern. Candidates who report choking typically describe preparing with 5-15 mock interviews. Candidates who report successful performance describe 30-50+ practice sessions.
This is not coincidental. Skill automaticity, the ability to perform without conscious monitoring, requires extensive repetition. When skills are automatic, they are resistant to choking because they do not consume the working memory resources that pressure compromises.
The problem is access. Traditional mock interviews require scheduling coordinators, finding partners, and working around other people's availability. Most candidates cannot practically achieve 50+ high-quality practice sessions.
How Rehearsal Solves the Access Problem
Rehearsal was built specifically to address the gap between required practice volume and practical access.
Unlimited Sessions: Practice as many times as you need. No scheduling constraints. No human availability limitations. The volume required for skill automaticity becomes achievable.
Consistent Stress Simulation: AI maintains consistent pressure across every session. It interrupts appropriately. It challenges statements. It does not go easy on you because you seem frustrated. Every practice session includes the stress elements that traditional mock interviews often lack.
Immediate Feedback: Know exactly what worked and what did not, immediately after each response. No waiting for mentor availability. The tight feedback loops that accelerate skill acquisition become standard.
School-Specific Preparation: Practice questions calibrated to specific IIM interview patterns. Understand how IIM-A questioning differs from IIM-L questioning and prepare accordingly.
Arousal Control Training: Built-in guidance on breathing techniques and stress management. The performance skills that traditional content-focused preparation ignores.
The Choice You Face
The Reddit post I opened with ended with a question: "I genuinely feel I can do much better than this, at least 95 percentile, if I handle my anxiety better."
That candidate is right. They could do better. The question is whether they will put in the work to develop performance skills, not just content knowledge.
Choking under pressure is not a character flaw. It is a predictable response to inadequate preparation for high-stakes performance. The candidates who convert are not inherently calmer or more confident. They have simply trained their brains to perform despite anxiety.
You cannot eliminate interview anxiety. But you can train your ability to perform despite it. This training requires volume practice under stress conditions with immediate feedback.
The 72 hours before your interview are not the time to start this training. The weeks before are.

Frequently Asked Questions
Q: Is interview anxiety normal?
A: Yes. Research on performance anxiety confirms that high-stakes situations trigger stress responses in nearly everyone. The difference between successful and unsuccessful candidates is not the absence of anxiety but the ability to perform despite it.
Q: How many mock interviews do I need to overcome choking?
A: Deliberate practice research suggests 50+ focused practice sessions for skill automaticity. Most candidates who report choking practiced with 5-15 sessions. Most who report successful performance practiced 30-50+ times.
Q: Can breathing techniques really help during an interview?
A: Yes. Tactical breathing research shows that box breathing (4-4-4-4 pattern) activates the parasympathetic nervous system and reduces cortisol levels within seconds. Navy SEALs and elite athletes use these techniques in high-pressure situations.
Q: What if I blank completely during an interview?
A: Use the reset phrase technique: "Let me put that more clearly" or "Actually, let me think about that for a moment." Panelists respect thoughtful pauses more than rushed, incoherent responses. Ground yourself by pressing your feet into the floor and taking one deep breath.
Q: How do I handle the night before an interview when I cannot sleep?
A: Lying in bed awake is more restful than getting up and doing activities. Do not check your phone. Practice slow breathing. Accept that you may not sleep perfectly and that one night of poor sleep will not destroy your performance if you have prepared adequately.
Q: Should I take beta-blockers or anti-anxiety medication for interviews?
A: This is a medical decision that requires consultation with a healthcare provider. Some candidates find medication helpful, but it does not replace the skill development that comes from practice. Medication manages symptoms; training develops capability.

Your interview is approaching. Your preparation determines your outcome.
The candidates who convert are not luckier or calmer. They trained differently. They practiced under pressure. They developed performance skills alongside content knowledge.
You can continue preparing the traditional way and hope your anxiety does not sabotage you. Or you can train specifically for high-stakes performance.
The choice is yours.
