I'm the Chief Executive Officer of Pksoftech Private Limited. the roles and responsibilities of a CEO vary from one company to another, often depending on the organizational structure and/or size of the company. In smaller companies, the CEO takes on a more “hands-on role”, such as making lower-level business decisions (e.g., hiring of staff). In larger companies, he or she usually only deals with high-level corporate strategy and major company decisions. Other tasks are delegated to managers or departments.
