Not being prepared and giving stock answers to questions are just two things that irritate interviewers, according to Alan Carniol, founder of InterviewSuccessFormula.com. Carniol advises job seekers to overdress for an interview to avoid being seen as unprofessional and to give memorable responses to set them apart from the crowd. "Interviewers likely go through hundreds -- if not, thousands -- of applications and meet with many candidates. If you aren't a shining star from the get-go, why should they pay attention?" Carniol writes.
