In my view the IAS is the best profession
The Indian Administrative Service is the premier administrative civil service of the Government of India. IAS officers hold key and strategic positions in the Union Government, States and public-sector undertakings. Like in various countries (example UK) following Parliamentary system, IAS as the permanent bureaucracy in India forms an inseparable part of the executive branch of the Government of India thus providing continuity and neutrality to the administration. Unlike Candidates selected to other civil services, a person once appointed to Indian Administrative Service or Indian Foreign Service(IFS) becomes ineligible to reappear in Civil Services Examination conducted by Union Public Service Commission because there are no higher civil services other than aforementioned two services under Government of India. Along with the Indian police and forest services, the IAS is one of the three All India Services—its cadre can be employed by both - the Union Government and the States. Apart from this IAS officials along with their counterparts from Indian Foreign Service are posted in various International Organisations like in the UN and it's agencies, World Bank and IMF etc . either representing India or working under them on deputations. They can also be deputed to relevant divisions of Indian Embassies and consulates along with Indian Foreign Service officers if and when required. Along with Indian diplomats they represent India or forms part of the delegations in Intergovernmental conferences and International summits. IAS officers at various levels of administration plays a vital role in conducting free, fair and smooth elections in India under the direction of Election Commission of India and state.
