Resume writing
What is a Resume?
A resume is a one page summery of your skills, education, and experience. The resume acts much like an advertisement for a company trying to sell something. The resume is your advertisement. Just as a company spends countless hours (and millions of dollars) designing their latest advertising campaign, you too must spend a good deal of time creating proofreading, editing, and perfecting your resume. A resume is one of the most important pieces of writing you will ever create. A solid resume is the key that will open the door to good jobs. Don’t cheat yourself … work hard on it.

How long do employers typically look at resume?
• Less that 30 seconds
• 8 mins
• 1 min
If you answered “A”, you are right. Employers often receive hundreds of resumes for a single position. They do not have time to read every word. This increases the importance of the smallest details.
What should be included in a resume?
Heading: Your heading should include the essential personal information. Your formal name (not nickname) should appear at the top. You want them to remember who you are in less than 30 seconds. Also include your address (both permanent and temporary) and phone number. If you use email, include your email address.
Objective (also called “Career Objective”): Employers often say this is the most important part of a resume. It is generally a one sentence explanation of the type of job you are seeking. Your objective should be fairy specific. If you are applying for different types of jobs, change your objective to match each type of job. If you are uncertain about the specific positions available, note your areas of interest.
Education: As students, this should be your next section of information. If you are in college, you only need to include college because it is assumed that you have graduated from high school. For the same reason, high school students shouldn’t include information from junior high/middle school. You should specify the dates of entrance or graduation (or expected graduation). As a college student, include the degree you expect to receive. Some people include education-related honors of this section. If your education is particularly relevant to a job, you may want to include a section titled “Relevant Courses.” In this category, you can list classes that might contribute to your employability.
Experience (also called “Work Experience” or “Employment Experience”): In this section, you should include previous employers, their locations, your dates of employment, and your job title. You should include at least two one-line descriptions of what your job duties and responsibilities were. You can not assume that the job title explains what you did to all readers. Use action verbs to start each of these descriptions. Do not use “I” in descriptions.
