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.
Functional Sample When you are referring the online resume samples, you will need a functional sample if you have employment gaps in your past. Functional format does not draw attention towards the gaps in employment history of the applicant. Rather it focuses on the existing skills of the applicant. It will explain to the employer about how these skills can help to benefit the company.
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.
