1.Work on your handshake: Don‘t offer up a flimsy or sweaty hand. Instead, when you meet with prospective employers or interviews, offer a firm handshake, with one or two pumps from the elbow to the hand. It‘s a good way to illustrate your confidence and start the interview off on the right note.
2.Get serious: If you take a casual approach to the initial interview with a company, especially with a screening interviewer from the human resources department, you may be sealing your fate. Job seekers should treat every interview as if it‘s their one and only chance to sell themselves to the recruiter.
3.Get the practice: If you find yourself being offered an interview for a job you are not really interested in, go on the interview anyway; you can make contacts for future job opportunities and get valuable interview practice.
4.Be enthusiastic: Bring a positive attitude to your interview. Most interviewers won‘t even give a second thought to someone who has a negative presence or seems like they almost need to be talked into the job. “You‘re selling yourself, and part of you is the positive approach you‘ll bring to the office every morning,” says Alison Richardson, a recruiter for several New York financial firms. “That smile and friendly demeanor go a long way.”
