Research before anything.
Find out as much as possible about the company's services, products and competition. Doing so will allow you to understand and address the business's needs, to better sell yourself in the interview. Understanding the company's culture will also enable you to gauge if you will be happy at your job.
Look Your Best
First impressions matter but dressing for an interview is not a one-size-suits-all matter. Depending on the company's environment, choose the best clothes suitable for it, and check for wrinkles and stains. After all, even if the company's filled with people in beach wear, you don't want to look like you've just climbed out of bed. Most importantly, you should feel good about what you wear. Because if you feel good, others will respond accordingly.
Be Prepared
Bring a folder containing extra copies of your resume, references and any other documents you may need. You should also have questions to ask at the end of the interview, and finally, have a paper at hand to take notes.
Be punctual
Never arrive late for an interview. Factor in extra time to find your way around the vicinity. It would be best to enter the building 10 to 15 minutes before the interview.
Listen
Listening is one of the most neglected interview skills. Additionally, don't just listen, but reading between the lines. Sometimes what is not said is just as important as what is said.
Answer the Question Asked
Make sure you understand the question before answering. If you are unsure, get clarification before answering. Sometimes, candidates don't think about whether they are answering the questions their interviewers ask.
Give Specific Examples
Prepare stories about your past experience before the interview. Give examples that highlight your successes. Your past behavioud can indicate your future performance.
Ask Questions
Many interviewees don't ask questions and miss the opportunity to find out valuable information. The questions you ask can indicate your interest in the company or job.
Follow Up
The follow up email is one more chance to market yourself and remind your potential employer about your best traits. Take it as an avenue to reiterate what you bring to the job and the company as well.
Show Enthusiasm and Confidence
Most importantly, be confident, give a firm handshake and plenty of eye contact. One way to show confidence is to be prepared to the best of your ability. There is no way to predict what an interview holds, but by following these important rules you will feel less anxious and will be ready to positively present yourself.
