Elon Musk bought Twitter in a much-publicised deal last year. The billionaire paid around USD 44 billion for the social media platform and introduced a number of changes the moment he assumed his new role. The first thing that he did was to fire the company's previous CEO, Parag Agrawal, along with other senior executives. Then, Musk introduced various changes in the company's work culture and asked employees to brace themselves for tough working conditions in order to build his 'Twitter 2.0'.
