Arrive Prepared There is a proper way of preparing yourself for the big day. Like I said earlier, asking for a proper schedule with the names and titles of the people interviewing you, would help you in doing some background research about them. You can search social network websites to gather more information about them. It will help you to relate with the persons involved. Knowing your audience will boost your confidence. Get enough sleep, and wake up feeling fresh... raring to go. Do not skip this step by any means, because in an all-day interview, you will not get a chance to get some shut eye. You will be expected to be agile and brisk all day long. Stock up on some emergency energy bars in case you don't get time to grab a meal. They will be filling and would also keep your blood sugar levels in check so that you remain alert. Keep some chocolates or candies handy for some quick energy on the go. The idea is to be active, even if you feel tired and sleepy. Each Mini Interview is Important For you, it's the whole day, but for each individual interviewer, it's one single stand-alone interview, in which he/she can decide your fate. Therefore, it is very important for you to remain active and cheerful during each and every mini interview. Based on the schedule that you got earlier, you have to prepare your beginning and end statements. Carry copies of your resume with you. In the beginning of each interview, greet the interviewer and see if he/she has a copy of your resume. If not, offer a copy of the same. These initial moments would serve as a warm up for the actual session. If the interview is conducted by your immediate head, or the colleagues of your prospective department, then be sure to end it with a positive statement that reiterates your interest in the position. A statement like, "I look forward to hearing from you", would make your exit a hit. With the rest, you can try different closings like, "All the best with the event next week." Never close the interview with a simple thank you and rush out. If you simply want to thank, make it grand by saying, "Thanks a lot for scheduling my interview, it was great to meet you." After all, the whole idea is to make each and every interviewer realize that he/she just spoke to the best candidate. Be Prepared for Giving Consistent Answers You will be asked about your experiences from previous companies. If you tell the same story to each and every interviewer, when they compare notes, they will be left with no other choice but to think that you didn't learn anything else from the last company. Therefore, when you have a chance to reveal different facets of your personality, why not do it with smartness? To start with, you can talk about the instance when you increased the sales of a product, to two of the interviewers. To the next one, you can talk about your public-speaking skills, and how you successfully presented a crucial presentation. To the fourth person, you can mention your problem-solving skills, and to the next two, you can speak about your participation in extracurricular activities like sports. The idea is to bring more things to the table. If you just give the same scripted answer to everyone, the interviewers may even think that the one thing that you told everyone could also be made up. Make Optimum Use of Breaks Impression matters a lot. You have to be calm and composed at all times. Your potential employer is watching you. If you show disinterest in any of the interviews, you may lose points of that interviewer. Morning interviews will be easy for you, but you are bound to be tired by the afternoons and evenings. When you are taking a break, you have to utilize those precious minutes to gather your thoughts back. If you are really nervous because the last interview didn't go too well, sit down and try to write the points that make you the most appropriate candidate for the position. By doing this, you will gain your lost confidence. You could quickly make a note of your achievements or just go through your resume. Take a few deep breaths, and calm your nerves. This point is really important, because, if you present yourself as a person who can handle stressful situations coolly, and can be peaceful at the time of chaos, you'll shine above your competitors who can't. Choose Food and Beverage Wisely For this day, you are allowed to ingest your daily dose of coffee, or may be a little more than that too. As the day starts fading away, your adrenaline levels also start decreasing. You find it difficult to gather your thoughts, and might start making mistakes. If coffee is your savior... indulge! It will keep you awake, and in the moment. If there is no coffee vending machine around, it would be wise to keep a few sachets of instant coffee with you so that you could at least prepare coffee with the hot water from the water dispenser. Whatever your routine pick-me-ups are, should be stocked up that day. You never know what can go wrong. But if you are allergic to coffee or have blood sugar problems, it is advised to stay away from it. The motto behind advising coffee consumption is simply to keep you on the go. If there are any other things besides coffee or caffeine that lifts your mood, you can stock on that. As far as food is concerned, choose easy-to-digest meals, and don't eat too much. Eating stomach full will make you drowsy. 'Just-enough' food should suffice for that day.
