Be courteous to everyone, everywhere all the time. Of course it should go without saying that you need to be polite to everyone when you are being interviewed. But you never know what cameras record in the reception area, or if your muttering in the restroom is unknowingly addressed to the hiring manager you are about to formally meet for the first time.
Hiring managers, human resources professionals and recruiters are all busy. Don’t be the person who keeps applying to the same job multiple times in the same week in order to keep popping up on the radar. When you are in an interview, keep your answers short, focused and to the point. Sometimes searches take longer than anyone anticipated. You can be sure that if you are the No. 1 candidate, you’ll be getting called along the way. Don’t allow yourself to be seen as a pest by overly frequent or demanding communications. Recognize that sometimes no news is simply that: no news.
Listen carefully to what people say. For example, it is typical for a hiring manager to describe the job or how the company goes about things at the beginning of an interview. It is the kiss of death when, later in the same conversation, you ask for information you’ve already been given. Of course, you can ask for a clarification or an expansion of an earlier subject, but don’t do so in a way that suggests you never even heard the information that a person has just conveyed to you!
Turn off your phone. When you are in a business meeting, nothing conveys a sense of “you’re not worth paying attention to” or “you aren’t my highest priority at this moment” than fidgeting with or answering your cell phone. Make a point of leaving your phone home, in the car or at least entirely turned off. Your interviewer deserves and expects your undivided attention.
Extend your appreciation, and promptly follow up all interviews. A thank you note is expected generally by email the same day as the interview, and certainly not longer than the next day. If you promise other information, such as references for samples of your work product, be prompt in supplying them. It is simply rude not to follow up and recognize the courtesies that have been extended to you.
