CAT GD PI 2026: Crucial Mistakes to Avoid in Group Discussion & Personal Interview

Things You Must Not Do During GD & PI Round

The GDPI round is an important part of post-CAT preparation. Here are some things you must not do during GD & PI Round:

• Be overconfident

• Be disrespectful

• Dominate discussion

• Lack confidence

• Be dishonest

• Lack professionalism

Importance of GD & PI Rounds

Before we discuss the things to avoid during your GD-PI, we need to see why this round is important. After the CAT results are declared, IIMs begin the selection process for their post-graduation programs. Your CAT score will determine whether you move on to the Group Discussion and Personal Interview rounds.

Once you get the required score in the CAT exam, you are called for either GD or WAT. The WAT is a brief essay writing competition. Then the candidate moves on to the PI round. The final selection will be based on the composite scores of candidates in all rounds. Your academic records are also taken into consideration. Co-curricular & extracurricular activities also play a role.

CAT GD/PI plays a very important role in the final selection process. It is crucial as the GD/PI round is given significant weightage in the final tally. The GD and the PI have an overarching theme. Basically, your personality and the way you handle yourself in a challenging situation is discussed because these show what kind of leader you can prove to be if you get the perfect grooming as in an IIM. The pattern of judging this may be different. The GD does this in a group setting whereas a PI tests this one-on-one. Your presence of mind is put to the test. As of now IIM Ahmedabad, IIM Bangalore, IIM Calcutta, IIM Indore, IIM Lucknow, and IIM Kozhikode have GD/PI rounds.

Common Mistakes to Avoid in Group Discussion (GD)

Errors in Group Discussions (GD) can have far-reaching implications for a candidate's performance in Personal Interviews (PI). Here are some go-to tips that you should follow to avoid the common mistakes in a group discussion.

Lack of Preparation

Lack of preparation spells doom. If you do not have knowledge of the topics on which you may be asked to speak, any other thing is of no value.

The GD topics are mostly from current affairs and the recent happenings in India and abroad. Get into the habit of reading the newspaper daily.

Simply knowing about the latest events around the world is not enough. Read multiple views on a particular topic and then form your own opinion about it.

Discuss important topics and current affairs with friends and mentors. Prepare arguments to defend your opinion regarding the important topics which may be asked in the GD.

The purpose of the GD is not to judge your mugging-up power but your decision-making skills and analytical reasoning regarding things in general.

Communication skills are important to convey your thoughts clearly and effectively.

Conduct GDs with your friends. Join a study group with friends to discuss current affairs and business topics.

Important GD Topics for CAT 2026

Overconfidence

Overconfidence is always a negative thing.

Being overconfident, you may not listen to and understand the arguments of others. A poor listener can never be a good speaker.

If you appear excessively overconfident, you appear to be arrogant.

Dominating the Discussion

Look for pauses in others' speeches to intervene when required.

You have to appear assertive but without overshadowing others. Do not be aggressive.

Do not try to monopolise the discussion. Also, be open to adapting your stance based on what others say.

Disrespectful Behaviour

Body language plays an important role in a GD.

Do not point fingers, thump on the table, lean back, knock the chair, twiddle your thumbs, or twitch while speaking.

Your body language should show your confidence, not aggressiveness.

Do not raise your voice too much. Do not interrupt or take away another person's chance to speak.

Using slang or inappropriate language is a complete no.

Dressing unprofessionally will be a sign of disrespectful behaviour.

Lack of Constructive Contribution

Things you should not do in GD and PI definitely include remaining silent.

You are not supposed to interrupt anybody, but you also have to find the perfect opportunity for yourself to speak.

If you are asked to make the summary, mention the good points made in the discussion and do not add any points of your side that were not discussed.

If you have not been able to speak during the GD, you are simply out of the race.

Common Mistakes to Avoid in Personal Interview (PI)

Mistakes in the Personal Interview (PI) round can significantly impact a candidate's chances of success. Poor communication, lack of preparation, and negative body language may create a negative impression. Here are some tips to avoid those while appearing for the CAT GD PI round.

Poor Communication Skills

Communication skills are the cornerstone if you are headed for GD PI. You need to practise your communication skills very well.

Work on speaking properly, pronouncing your words correctly, and changing the tone of your voice.

Remember, pronunciation and accent are two different things. Pronunciation is the right sound of a word and accent shows which country, area or social class a person comes from.

Stuttering and fumbling will have a negative impact because both these things show lack of confidence.

• Speak slowly.
• Practise speaking slowly daily.
• Reading aloud at a slow pace also helps.
• Try taking deep breaths just before you enter the room where you are to be interviewed.

Lack of Confidence

Your lack of confidence may be evident from gestures like fidgeting, jittery leg movements, your sitting posture and eye contact.

• Nervousness not only creates a bad impression but also adversely affects your performance.
• Confidence does not come in isolation. You need to work diligently on your interview preparation.
• Ask someone to conduct a mock interview with you, role-playing as the interviewer.
• Record your practice sessions to assess your delivery, clarity, and body language.

Being Dishonest

You may be tempted to exaggerate your achievements and qualities in the interview but remember, it has its own risks.

If you are caught lying or giving any false information, you stand a strong chance of being disqualified from the PI.

If you do not know the answer to a certain question, do not try to fool the panel with a play of words. It is better to simply admit, "Sorry sir, I don't know."

Inadequate Preparation

• You need to know your own resume inside-out as many questions can be formed on its basis.
• If you have mentioned some achievements on your resume, you can be asked to elaborate on them.
• If you have any drop year, be ready to explain the reason for it.
• If you switched to a different field/area of interest, prepare an answer for it.
• You may be asked about your family, city, work experience, future plans, goals, and "Why MBA?"

Be well prepared with the current happenings around the world and evergreen topics like brain drain, inflation, unemployment, women empowerment, and wage disparity on the basis of gender.

Lack of Professionalism

It is essential that you present yourself in a polished and professional manner.

• In no way should you be late for your interview.
• Dress appropriately for the interview. You need to follow a proper formal dress code.
• Be well groomed and wear nicely polished shoes.
• If girls wear any jewellery, keep it minimal and simple.
• Makeup, if any, should be very light and decent.
• It goes without saying that you shouldn't use slang in your interview. It is totally unprofessional.

Avoid using fillers. Filler words allow speakers time to pause and consider what to say next. Often, speakers develop habits of using the same filler words when they need to organise their thoughts like “I think, you know, like.” Reducing the use of distracting language, like using filler words, can also add confidence and clarity to your spoken communications. Using filler words frequently, especially in a professional setting, can inhibit your ability to communicate clearly as the interview panel may be distracted by your intermittent use of fillers. The presence of lots of filler words can suggest that you might be nervous. The more you work on your spoken English with practice, the less you will feel the need to use fillers.
