Most interviewers form their opinion of you in the first few minutes of a meeting. And undoubtedly, your interview will create an impression that will last throughout your career at your employer. So it is very important that you be prepared to nail it well!   Here’s how to make a good impression.

In the days before your interview, talk to people who have worked at the company. If it’s practical, hang around outside the building while employees are arriving and note how they dress and behave.

Learn the name and title of the person you’ll be meeting with. Arrive at least 10 minutes early to collect your thoughts.

Take time to greet and acknowledge the secretary or administrative assistant; it's old-fashioned courtesy, and besides, this person may have a lot of influence.

Bring along an extra résumé and letters of recommendation in case the interviewer doesn't have them handy.

Be open and upbeat. Face your interviewer with arms and legs uncrossed, head up, and hands and face at ease. Smile and look the interviewer in the eye.

Know the company's business, target clients, market and direction cold.

Walk in prepared with a few relevant questions and listen carefully.

Subtly give the impression that you're already part of the team by using "we" when asking how something is done. For example, say, "How do we deal with the press?"

Conclude with a positive statement and a quick, firm handshake. Ask when you might follow up, and get a business card from the interviewer.

Send a thank-you note.
