    Take note. These commonly made mistakes could cost you your dream job.

    We've all been there. Trying to be the most impressive version of yourself while having your competence questioned by a high-flying boss-person is stressful.

    Research conducted by Barclays Lifeskills reveals that a quarter of young people believe they perform badly in interviews and 64 per cent say they would benefit from job interview training.

    Plus, even if you think your communication skills are on point and your charm is off the charts, that alone is not enough to win you your dream job.

    Barclays' Lifeskills team surveyed 500 interviewers in order to determine what are the most common errors made by job candidates at interview. The most frequent mistake? A failure to prepare properly.
