Yes. An effective cover letter should first introduce you as an applicant to a specific job. You should then explain your qualifications for this position and conclude with a request for an interview. You should also take this opportunity to explain any potential concerns including employment gaps, brief employment periods and any other items that could be perceived as negative. Remember, in the absence of supporting information, employers will assume the worst.
We do not require cover letters if you use our services. Our recruiters facilitate introductions that take the place of cover letters. We are your strongest advocate.
