If you are looking for a job you need a resume. Even if you are applying for a job in Burger King bring a resume. Your resume should have your name, address and phone number on it. Do not put cell phones on there because if a potential employer calls you on it and you don't have the greatest reception, it is going to be a big turn off for them. You don't need to date the resume, when you send a cover letter with it you can date that page.
The next thing you want to put on there is your objective, try to keep that to one or two lines. Keep it to the point. Try to make an objective where it will benefit the employer as well. You want to keep the entire resume contained to one page, if you have to go to two keep it short. There is no interviewer who wants to read a multi page resume.
Next thing to should have is your experience. Some resumes have education first, this can go either way but a potential employee wants to see what you can do and what you were doing before applying for the job. Don't make them scan it; put it first where they could see it. List your last job first and so on. Tell them what they want to know in a couple of line. Put the company name and location, just the city will suffice. Then only put the years at the end of that line. Give a brief description of that job and list the important functions first.
Then is the education section, if you have been out of high school for more than 10 years, there is no need to write it. The same goes for job experience, don't list jobs you had more than 6 years ago. They don't want to see that far back. List the most recent school last and so on. If you did not go to college or are in the process of going, leave open the year to at the end. For example, XYZ University, Any town, USA 04 to .
Then you can list any achievements or special citations you have received pertaining to work. Then you can write down References available upon request. Make a list of 5 references; try to make them professional references.
