Guardsmark has a slow and thorough process. Several levels of review are required to secure the job and there is very little communication in between time. Local management may like a candidate but lack the authority to execute on the hire which can be frustrating. But after enough time things eventually roll around. Make sure your background is squeaky clean. The drug test is no job, there can be no gaps in your employment and every reference and previous employer will be contacted...not too mention the MMPI.
