The Department of Homeland Security (DHS) hiring process typically begins with an application through United States Department of Homeland Security and the USAJOBS platform. Candidates usually go through several stages, including assessments, interviews, and job-related tests, followed by extensive security screening, drug testing, and background investigations. The process is highly competitive and can take anywhere from several months to more than a year, usually starting with a tentative offer before a final job offer is issued.
