Start your prep the day before the interview.
Know who you are talking to. Do some research. Google them.
Know about the company. Find their web page and read it.
Clean out your car…many companies will check out your vehicle for cleanliness and hints as to your personality. Remove any tools, toys or clutter that might help them out. Or add things that might help you out. Applying at Publix? Put a Publix bag on the seat in plain view. If you have time – remove any offensive bumper stickers. You can find tips on how to do that quickly online.
Dress yourself appropriately. A polo shirt and slacks will work for most blue collar interviews. A dress shirt, blazer, tie, and slacks are good for white collar interviews. Tee-shirts and sweats are NEVER appropriate. And pay attention to your shoes.
Wear a watch – even if you usually don’t. A watch implies you are time conscious and suggests you are not a cell phone addict.
Speaking of which, leave the cell phone in your glove box. Period.
When entering the office, move something, even if it is just a chair this will make you feel more in control and also signals the interviewer subconsciously that you feel like you, not he/she is in control.
When asked a question –
Start by repeating the question in a rephrased form
This suggest you understand the question.
Answer the question clearly and concisely – blue collar
Answer the question with a short clear story – white collar
This shows you respect the other persons time – blue collar
This shows you are capable of linear narrative thought
Create a personal association
For yourself and the interviewer
Feign NT sincerity – and try to be sincere
Make eye contact, mirror the interviewers gestures, nod, smile or frown appropriately
Use silence as a tool
This gives you time to think and also suggests that you are comfortable and alpha in the situation
If you studied this will really help you out here
NEVER lie or pretend to knowledge you do not have
If you are caught, you’re screwed and the person across the desk will feel insulted.
If you really do not understand ask a question
This shows you actually care about the job
Avoid all swear words and slang
This makes you look and sound more professional
When you leave thank the interviewer/s for their time and wish them well
When you get home send a followup thank you email or note thanking the person for their time
