Dress professionally. Yes, presentation counts. You are trying to make a good first impression. Dress for success!
Remove all face or tongue piercings.
Turn cell phones off. Make sure it’s off, double, triple check!
Show up early but not too early. While you should give yourself plenty of time to show up for your interview showing up thirty minutes early just is not good business. A good rule of thumb is to show up ten minutes early for your appointment. Show up alone, don’t bring family, friends, or children to an interview.
Attitude. Have a good attitude. Be polite, excited, and energetic. Remember to smile and keep good eye contact. Be courteous to your interviewer and also to others in the office, even the receptionist.
Be honest and keep the conversation on business only. Do not share too much personal information. Sometimes individuals want to share too much especially if it is a sad story. Try to keep it all business-related. Same with your resume, be prepared. Know the company and why you want to work there. Research the company and be knowledgeable.
Bring a copy of your resume and a notepad. Your interviewer(s) will likely have a copy of your resume but bring spares. It shows you are prepared and serious about getting the job. Very few people bring a notepad with them to a job interview. It is a very subtle thing that makes you stand out. Take notes when appropriate.
Set all internet profiles to private. If you do not think interviewers Google you or look you up on Facebook or MySpace, you’re wrong. Hiring managers do this to weed out people who would not be a good fit in the company. Do not make jokes, or write vulgar language where people can view them or could be offended. A job interview is not the place to test your material. Be friendly and outgoing, save the jokes.
Do not badmouth a boss. Bad mouthing a previous boss in a job interview is a huge negative. They may have been the worse boss in the world but expressing that in a job interview is a huge mistake. Some things are better left unsaid.
Do not flirt with the interviewer. Common sense but apparently needs to be stated. Do not play with your face, hair, etc. Interviewing can be a nervous experience but rubbing your chin, twirling your hair, or anything else along those lines makes you look like you are lying or lacking confidence.
Be clean and have on clean clothes that are pressed. Do not walk in smelling of cigarettes or overloaded with perfume. Less is more. Maintain good eye contact. Staring at the floor, ceiling, or wall when speaking or listening makes you appear disinterested. Again, simple and obvious but happens way more than you would think. Be prepared to talk about something that you are proud of accomplishing. Whether professionally or personally (or a failure and what you learned from it).
Ask questions at the end of the job interview. Make sure you have some questions to ask. If the interviewer does not offer you a chance, ask to ask. Again, it reinforces your strong interest in the job. Send a thank you note. It is easy to send an email but take the extra effort to mail your interviewer a handwritten thank you note. It reinforces your interest in the job. It does not need to be long, just make it sincere.
