Be nice to the people you meet at an interview
I’ve done some interviewing in my previous life, and a question I always asked of our receptionist was “what did you think of the person that just interviewed?” Were they polite and courteous? I’m not saying to go overboard when you meet the people at your potential new employer. What I’m saying is to always be polite and courteous to everyone you meet, whether it is the security guard at the door or the manager’s assistant. Say please and thank you, and when you are leaving say goodbye. As my mother would say good manners are important. Be sure to use them on your interview. It might be a small thing, but that manager might just ask his or her assistant they’re opinion of you.
