Meta Platforms Inc started carrying out the last batch of a three-part round of layoffs yesterday, according to a source familiar with the matter, as part of a plan announced in March to eliminate 10,000 roles.

Meta earlier this year became the first Big Tech company to announce a second round of mass layoffs, after showing more than 11,000 employees the door in the fall. The cuts brought the company’s headcount down to where it stood as of about mid-2021, following a hiring spree that doubled its workforce since 2020, Reuters reported from New York.

Several employees working in teams such as marketing, recruiting, engineering and corporate communications took to LinkedIn on Wednesday to announce that they were laid off.

Meta Chief Executive Mark Zuckerberg in March said the bulk of the layoffs in the company’s second round would take place in three “moments” over several months, largely finishing in May. Some smaller rounds could continue after that, he said.

Overall the cuts have hit non-engineering roles most heavily, reinforcing the primacy of those who write the code at Meta. Zuckerberg pledged in March to restructure business teams “substantially” and return to a “more optimal ratio of engineers to other roles.”

Even among cuts aimed specifically at technology teams, the company eliminated non-engineering roles like content design and user experience research most severely, according to executives speaking at a company town hall afterward.

About 4,000 employees lost their jobs in the April layoffs, Zuckerberg said during the town hall, following a smaller hit to recruiting teams in March.
