A good resume is the first step in the right direction. After all, it is your door opener and it is the first opportunity for the potential employer to judge how well you present yourself. In order to prepare a good resume, there are some basic rules to follow:

Length
A resume should be a precise and concise document. As much as possible, a resume should not be more than three pages.

Content
Keep it clean and tidy. You should separate your resume into sections including personal information, qualifications and employment history. All the important information such as your current position and qualifications should be on the first page.

• Personal Information - Include your name, address, contact number, e-mail and date of birth.
• Qualifications - List all the qualifications you have in chronological order, starting with the most recent one.
• Employment History - Start with the most recent position, includes your job responsibilities, duration of employment and achievements. As much as possible, highlight your accomplishments in a bullet point format as it delivers a clearer and more powerful message. 

Layout
Layout and design should be consistent and easy to read, with good clear headings and fonts. Do not use fancy borders or coloured fonts as it does not add any value to your resume and often it demonstrates your lack of professionalism. Do write in plain English so that even non-technical interviewers can see what you have done.

Last but not least, you should always be honest with yourself and do not claim complete responsibility for accomplishments, as this is usually a team effort and not individual achievements.
