Proof of Eligibility to Work All new employees are required to provide proof of eligibility to work in the United States within the first 3 days of employment in order to comply with the Immigration Reform and Control Act of 1986. Applicants are encouraged to bring a resume to the examination to use as a reference when completing education and experience portions of exam. Veterans may be eligible for preference points on exams. To determine eligibility, provide a copy of final DD214 which displays branch of service, dates of service, and character of discharge. Calculators will be provided, as needed.
Examinations are generally open only to U.S. citizens who are Illinois residents.
How Jobs are Filled Applicants who pass an examination are placed on the Civil Service employment register for that job title, in order by score. When there is a vacant position for a specific title, candidates are referred to the employing department for an interview, in order of their ranking. The employing department conducts interviews and makes a hire decision. Probationary Period Civil Service employees are required to complete a probationary period of either 6 or 12 months duration, depending on the job title. The probationary period is designed to provide an opportunity for the employee to demonstrate the abilities needed to perform satisfactorily in the position.
