The most important thing to do for an interview is prepare!
Make sure you are armed and ready to answer any and all the questions posed by a potential employer. The better prepared you are means the less nervous you will be, the better impression you will make and the better chance you have of securing the job.
Be on time. Know where you are going and how to get there. Prepare for delays in your travel.
Review your CV and if possible have it close at hand for reference. Be able to discuss your skills and achievements in detail and with confidence. Be specific about your strengths and experience.
Research the company. It is very important to have good knowledge of what the company does, their history, business culture, and their plans for the future. Make note of recent changes in the business, or the launch of new products and services. This shows initiative as well as interest in the work and the company. The more relevant things you can discuss with your interviewer, the better.
Be polite, friendly, and remember your manners! Address the interviewer as “Mr” / “Ms” or “Dr” until they tell you to call them by their first name. It should go without saying, but don’t swear and don’t use slang. It is important to be personable and likeable while being professional. Be yourself, but be the best possible version of yourself. Employers simply do not want to work with people they don’t really like.
Often your first interview with a company will be a telephone interview. Prepare for these as you would for a face-to-face. Make sure you have confirmed who will call who and at what time. Take time differences into account – ie 3 pm German time is 2 pm in the UK. We always suggest standing rather than sitting during the call as it makes you more alert and focused. Have a glass of water with you. Speak clearly and pay attention to avoid “ums” and “uhs”. All the rules that apply to face-to-face interviews still apply for telephone interviews!
