I often review and critique 5-10 resumes (or more!) daily.
If you are not quite ready to work with a professional writer, here is a great checklist I have complied to help you critique, and improve your own documents.
Resume Critique Checklist Remember, you generally have anywhere from 5-15 seconds to engage the reader.
Your documents must be clear, concise and interesting! So if you want to improve your chances of getting an interview -- be sure you can answer yes to ALL of the following questions: First Impression

• Does the resume and cover letter look original and not based on a template?
• Is the resume inviting to read, with clearly labeled sections and ample white space?
• Does the design look professional and appropriate for your industry?
• Is a qualifications summary included at the top so the reader immediately knows the applicant's value proposition?
• Is the document's length and overall appearance appropriate given the career level and objective? (Note: Unless you are in Academia, or preparing a detailed CV, keep your document to no more than two pages)

Appearance

• Does the resume look polished, visually pleasing, and professional?
• Is the font appropriate and easy to read?
• Are there design elements such as strategic bolding, capitalization, bullets and lines to guide readers' eyes through the document and highlight important content?
• Are margins even and well balanced?
• Is there enough white space?
• Are font size, spacing and date format used consistently throughout the document?
• If the resume is longer than one page, does the second page contain a heading? Is the page break formatted correctly?

• Are sections placed in the best order to highlight the strongest credentials and industry-relevant information?
• Have you included a keyword-rich skills/core competencies section?

• Is the summary or headline geared towards your value proposition, and not all about what YOU want?
• Is the resume geared to a specific career goal, industry, or position and not trying to be a one-size-fits-all document?
• If this is a resume is facilitating a career change, is the current objective clearly stated, with details demonstrating how past experience is relevant to the new career?

Accomplishments

• Does the resume include a solid listing of accomplishments, not just duties?
• Are accomplishments explained using specific numbers, awards, percentages, dollar amounts, etc.
  ?
• Do accomplishment statements begin with enticing, strong and varied action verbs?
• Do listed accomplishments tell a good career story and demonstrate value?

Relevance

• Is the information relevant to the company and position's needs?
• Does the content support the career goal?
• Is the resume keyword-rich, filled with with industry buzzwords and appropriate acronyms?
• Are awards, professional affiliations and relevant volunteer experience included, while personal information like marital status, age and nationality and personal references omitted?

Writing Style
