Your personality is, on an average, assessed in 25-30 minutes, it is your responsibility to bring out your very best in front of the board. Be attentive and listen to each question carefully. Try not to jump into an answer before the complete question has been posed as you will end up wasting time on answering a question that you were not actually asked. If you are not sure of what was asked, you can always politely seek a clarification. Do not try to answer the question as soon as it is posed. Think over the question, take your time and organize the broad outline of the answer before airing it. Pause a while before answering, even if you know the answer. Your replies should be crisp and to the point. Do not beat around the bush. Accept your mistakes boldly. It is better to say ‘No’ than to bluff around. Speak honestly, truthfully and modestly. Don’t try to be too argumentative. Take tea or coffee, if any member offers the same to you. This will show you are relaxed and it will also help in lightening and relaxing further proceedings and give them an informal touch. Don’t criticize any government policies or even individuals.
