Do you send out resumes or complete applications and hear nothing back? Do you have great interviews and then never hear from that company again? Chances are you have a bad reference. Employers usually check references before a person is hired, though some results might come back after you are already employed. Don't let a bad reference sabotage your potential new job. Let a company do check your employment references and personal references.
