One of the first things to know before an interview is that it is an integrated assessment of your personality, energy, enthusiasm, intelligence, knowledge and experience for the job you are being interviewed for.
The dress attire should be formal, neatly ironed clothing with no flashy colors, such as a bright, multicolored necktie ora wrinkled dress. A detailed knowledge of the subjects related to job description, a history and profile of the company, as well as some knowledge about the interviewers themselves, is very helpful.
Regular exercise and meditation, especially for a few weeks before the interview, is indispensable towards marketing yourself as an energetic and dynamic, yet calm and peaceful person.
You should get plenty of sleep the night before the interview and make sure you do not overeat during breakfast. Consume plenty of fluids and make sure you have a list of all the items you would need during the interview beforehand.
If possible, it is best to carry a laptop with a well designed PowerPoint presentation, a few copies of your two page resume, and at least ten copies of your business cards —preferably with a one inch by one inch size photo printed on them. It is also helpful to have a folder containing your credentials, degrees, and a detailed summary of your past work experience.
You should face the interviewer with a calm demeanor and focus on the questions given by looking directly in the interviewer’s eye. Make frequent eye contact and shift your eyes from the interviewer’s forehead and hair to their eyes and nose while answering your question in a clear and succinct manner.
If you do not know an answer to a question, be frank and honest and ask the interviewer if you can get back to them with the answer at a later time. Do not be cocky or arrogant; rather, exude confidence through your knowledge and experience to help secure the job.
