There are three primary types of civil service:
1. Merit-based civil service: This type of civil service is based on a system of merit, where candidates are selected based on their qualifications and abilities, rather than political connections or other factors. This is the most common type of civil service in many countries, including the United States.
2. Patronage-based civil service: This type of civil service is based on political connections and favors. In this system, political leaders appoint their supporters and allies to government positions, regardless of their qualifications or abilities. This type of civil service is less common today, but was prevalent in many countries in the past.
3. Mixed civil service: This type of civil service combines elements of both merit-based and patronage-based systems. In some cases, political leaders may use their influence to appoint candidates to government positions, but these candidates are still expected to meet certain qualifications and standards”
