The summary consists of the following blocks:
Your name, address, phone number (including area code).
Purpose (optional, but desirable): a brief description of what position and why you are applying for (no more than 6 lines, but 2-3 is better).
Work experience in reverse chronological order (last job listed first). This is the main part. Indicate the start and end dates of work, the name of the organization, the title of the position (there may be several of them if your career developed successfully), and briefly describe the job responsibilities and production achievements, if you had any. When describing your accomplishments, use action verbs such as developed, saved, increased, or reduced.
Education (the more time has passed since graduation, the less space this item should take in the resume; for graduates and students, it should be placed before the previous one, since work experience, if any, is less significant, you can report awards, emphasize those studied disciplines that correspond to your goal).
Additional information: knowledge of foreign languages and a computer, possession of a driver's license, membership in professional organizations, etc. (a hobby should only be mentioned if it is closely related to the desired job). Indication of the possibility of providing recommendations.
