The interview is often the stage of the job seeking process that most people hate. An excellent way of overcoming nervousness is to feel confident about the interview process.
Before attending an interview always carry out plenty of research on the company. The first question most interviewers ask is "Do you know anything about the company?". Nailing the first question will help you relax and feel confident. Most people will answer "no" so by demonstrating your knowledge of the company background you will catch the interviewer off guard. Trust me they will be impressed.
2. Interview Questions
Search online for sample interview questions. Also, think about questions you have been asked about in previous interviews and prepare answers. Run through the sample questions and make sure you are confident answering them.
3. Research Yourself
Employers will conduct background checks even if that is just looking up your social media profiles and running a quick Google search.
It is often best to do this before you start applying for jobs but doing it is never too late. Make sure your social network profiles are either private or professional. If there is anything that you would be embarrassed by an employer seeing, it is not professional, make your profile private.
If you find anything via a Google search you are embarrassed about, Google can offer some support in getting it removed from search results.
4. Learn Your CV
This sounds obvious but you would be surprised at the amount of people that cannot recall the dates they worked in a particular role or can't fully explain what they did at a company.
Knowing your work history and professional life well will prevent any awkwardness in the interview.
The best way to build confidence is to practice the interview before the big day. If you have a friend who can play the role of the interviewer great, but this is not essential. Practice in front of the mirror if you have no one to help you. Speak aloud while checking your body language and facial expressions.
