Twitter, the tech giant headquartered in San Francisco, is undergoing a major upending phase — coming to a head internally as two major executives are seemingly being pushed out and the company ceases all hiring.

According to a companywide memo obtained by Bloomberg, the company will stop hiring new employees — and may even rescind offers already made to candidates. This news comes as two Twitter executives, general manager of consumer product Kayvon Beykpour and general manager of revenue Bruce Falck, were asked by Twitter CEO Parag Agrawal to depart the company. Some outlets reported Falck and Beykpour were fired, but the exact details of their departures are unclear.
