Job experts have explained that you can 'fail' an interview in the first seven seconds, and have pointed out a common mistake that many people make. Research suggests that employers often form their initial perception of candidates within the first seven seconds of meeting them, called the "7/11 rule”.

Within the first seven seconds, interviewers form 11 impressions on traits like your credibility, likability, and competency. Dr George Sik, a leading psychologist and Director of Assessment at eras, shared five common mistakes candidates make in those initial moments, and how to avoid them.

He said: “Securing a job offer is fiercely competitive, with an average of 118 applicants vying for a single position. Getting the basics right from the start is crucial. You've got just seven seconds to make a strong first impression, and 65% of hiring managers form their initial opinion of you within the first few minutes of the interview.”

The Fumbled Entrance: “Being late is the first big no-no, as this shows a lack of respect for the interviewer's time, and can create a negative first impression. Arrive early, greet everyone confidently, and take a deep breath to compose yourself before entering the interview room.”

The Unprepared Answers: “Nearly half (48%) of UK hiring managers feel put off by a candidate arriving unprepared or flustered. Failing to research the company and the position can make you appear uninterested. To avoid this mistake, thoroughly research the company's background, mission, recent news, and responsibilities. Practise answering common interview questions with examples from your past experiences. It’s equally important to ask thoughtful questions to show your enthusiasm and gather information about the company and role. Prepare questions that demonstrate your interest in the company culture and role expectations.”

The Weak Body Language: “Your body language speaks volumes during an interview, so it's crucial to be mindful of how you present yourself. Darting eyes can signal nervousness or untrustworthiness while maintaining eye contact demonstrates engagement and interest. Avoid common body language mistakes like slouching, fidgeting, and a limp handshake, as these can convey nervousness or lack of confidence.”

The Negative Talk: “Don't walk into the interview already defeated! Project confidence with positive body language and a smile. Refrain from speaking negatively about past employers or colleagues, as it can raise concerns about your attitude and teamwork.”

The Rambling Answer: “Prepare concise and clear answers to common interview questions to avoid rambling or going off on tangents. Avoid generic, one-size-fits-all responses, as employers want to see how your skills and experiences match with the role.”

George said there is also one often overlooked tip that leads to a common mistake. He said: “Many candidates don’t follow up with a thank-you email or note after the interview. Sending a personalised thank-you message within 24 hours of an interview shows appreciation and reinforces your interest in the position. Keep it concise, professional, and error-free.”
