Be honest Never lie or stretch the truth on your resume. If your employer finds out later you will probably be terminated. If your resume is lacking in some areas build those areas up honestly by increasing your skills instead of pretending. The truth will always come out eventually and it usually hurts you in the end.
Review the Job Posting and Description Carefully A lot of the time job-hunters will write one generic resume and send the same generic resume to every employer. This is one of the biggest mistakes facing job seekers because it produces so-so resumes that dont necessarily match the employers requirements.
Functional format is best for those who are switching their career or have large employment gaps on their resume. In this format, you dont have to list the joining or resigning dates of the previous employments. Functional format will hide your employment gaps or your job switching.
Make your resume original Make sure your resume stands out from the crowd. Dont be afraid of trying something different or breaking from the mold. Sometimes a little creativity can garner enough attention to get your resume read which can make all the difference. Dont overdo it though. Being wacky or silly may be a part of your personality but usually is not a desirable quality in the work place. Photos are usually a bad idea as well. Be creative but keep it simple to avoid drawing attention away from what is really important.
Use proper formatting Make sure to avoid excessive white space and to use the space on the page. Avoid using more than one page if possible definitely no more than two. Highlight key points with bullet lists and make sure your paragraphs are clear and concise. Resumes are not the time to be wordy. Be straight to the point.
