We use iCIMS at Vology as an applicant tracking system. We house all of our internal and external (and confidential) recruiting activity within the tool. It is used solely within our Human Resources department. It allows us to post jobs to any job board directly from the ATS, and track the workflow of candidates through various steps of our recruiting process, it allows us to perform batch actions such as sending thank you letters and rejection letters. We also utilize iCIMS for a completely paperless onboarding process, allowing candidates to complete all of their new hire paperwork - both the standard W-4 and I-9 requirements as well as customized policies and Vology-specific forms - on their own time before their first day. This saves lots of paper and time, and houses the forms permanently in the employee record within iCIMS, eliminating the need for paper records. At Vology I am the main user of the system and we fill about 55 jobs/year. We also use it for AAP reporting at the end of the year, as well as other custom reporting of data such as source of hire, time to fill, etc.
I also used iCIMS at a prior company - Sage - where we used the system across a large enterprise of 5,000 employees, filling hundreds of jobs each year. At Sage, we also used the tool to feed directly into the HRMS system, automatically creating employee files and payroll records with simple clicks.
iCIMS is a tool that allows for the organization of candidates who have applied for jobs, it creates a searchable database of candidates for your organization, eases recruiting transactions, communication with candidates, reporting on talent acquisition activity and it is the first step in taking your entire HR department paperless.
