Most job seekers know that making a good first impression in a job interview is crucial, but they may not realize how little time they have to do it.

A new survey from Canadian job site CareerBuilder.ca finds that nearly half (47 per cent) of employers say they know whether a candidate is a good or bad fit for the position within the first five minutes of the interview. By the 15-minutes mark, 87 per cent have determined if the job seeker is a good or bad fit.

The national survey was conducted online from November 6 to December 2, 2013 by Harris Poll on behalf of Careerbuilder.ca and included a representative sample of 406 hiring managers and human resource professionals across industries and company sizes.

“Employers want to see confidence and genuine interest in the position.

“Going over common interview questions, researching the company, and practicing with a friend or family member can help you feel more prepared, give you a boost in confidence, and help calm your nerves.”
