കമ്പനി കോർപറേഷൻ അസിസ്റ്റൻറ് പരീക്ഷയുടെ തിയതിയും സിലബസും വന്ന കാര്യം എല്ലാവരും അറിഞ്ഞു കാണുമല്ലോ. മെയ് 12 ന്  നടക്കുന്ന പരീക്ഷയിൽ പ്രധാന പ്രത്യേകത സോഷ്യൽ വെൽഫെയർ സ്‌കീമുകൾ സിലബസിൽ ഉൾപ്പെടുത്തിയിട്ടില്ല എന്നതാണ്. പകരം IT ആൻഡ് സൈബർ ലോ ആണ് ഉൾപ്പെട്ടിട്ടുള്ളത്. അതിനാൽ ഐ റ്റി, സൈബർ ലോയുമായി ബന്ധപ്പെട്ട ചോദ്യങ്ങളാണ് ഇനി നോക്കാൻ ഉള്ളത്.
