A big part of a successful interview is avoiding simple mistakes. You can learn from the mistakes of others and avoid these top 10 worst interview mistakes.

Badmouthing your boss

49% percent of hiring managers cited badmouthing a former boss as the worst interview offense. Don't speak negatively about your former boss or company. It’s the fastest way to talk yourself out of a job. Instead, put a positive spin on your experiences and your job search.

Not being prepared

If you really want the job, you need to do some homework. Find out all you can about the company, using their website. Read press releases to find out about their products, customers and competitors. Demonstrate your interest with a few questions to the interviewer that reflect your knowledge of the company.

Sounding too rehearsed

While it’s important to practise your answers, try not to sound too rehearsed. When you are practising, write the answers in bullet points which will stop you memorising information word-for-word.

Not knowing yourself

Make sure you know what sets you apart from other candidates and be specific about what you've done that has made you successful. Know your background without having to refer to your CV. There is no one better than you to tell your story.

Talking too much

There is nothing much worse than interviewing someone who goes on and on. The interviewer really doesn't need to know your whole life story. Keep your answers succinct, to-the-point and don't ramble. The best way to do this is to prepare and practice your interview answers beforehand.

Focusing on the past

The projects you worked on ten years ago bring context to your career and the professional you have become. However the skills you now possess are what will be valuable to your new employer. Concentrate on your current roles and experiences.

Lack of enthusiasm

This is your first and sometimes only chance to showcase your personality. Be polite and upbeat. Show your enthusiasm for both the job and the company. Focus on positive topics and achievements.

Exaggerating work experience

Recruiters know if you're exaggerating in interviews by vague responses, missing information and inconsistencies. If there is anything that appears odd, they will ask the same question in various ways. If you are telling the truth your answers will remain consistent.

Not removing unprofessional photos/content on social networking sites

With the popularity of social networking sites, it’s easier than ever to find personal information about candidates. Don’t give a potential employer a reason to doubt your credibility. If you have a Facebook page keep it clean or make it private.

Not asking questions

Having no questions indicates that you have not thought much about the position. Prepare at least three questions to ask the interviewer. One of the most effective questions to ask is: “What do you think my biggest challenge would be in this position?” You can discover if the interviewer has any concerns about you and can address these there and then.
