Avoid being vague If you have references include them. Dont say available upon request. If you have gaps in employment explain them clearly. They will probably come up in the interview anyways. Being prepared in advance by giving complete information in your resume is better than being caught off guard in the interview or worse skipped over all together.
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.
Always include a cover letter The cover letter is your time to highlight your skills and sell yourself as well as your resume to the recruiter. Make sure to use power statements and highlight your best qualities to get their attention. Your cover letter should address all the requirements for the position and explain why youre the best person for the job.
