A state-owned enterprise is called a public sector undertaking (PSU) or a public sector enterprise. These companies are owned by the union government of India, or one of the many state or territorial governments, or both. The company stock needs to be majority-owned by the government to be a Public Sector Undertaking. PSUs may be classified as Central Public Sector Enterprises (CPSEs), public sector banks (PSBs) or State Level Public Enterprises (SLPEs).
PSU’s recruitment rules are changed from time to time. From year 2013 onwards almost every PSU is recruiting through GATE exam. And few other PSU’s are taking their own exam. Government of India revised its rules and regulations and classified the PSUs in several categories as follows:
