In the third round of layoffs, Twitter has laid off about 40 advertising team engineers and data scientists

According to foreign media reports, Twitter laid off about 40 advertising data scientists and engineers on Wednesday, at least the third round of layoffs since mid-December last year.

It has been revealed that the layoffs are aimed at what Twitter management sees as "areas of failure" and unimportant areas of business, such as advertising products and data science.

Twitter's advertising revenue has fallen sharply in recent months. In addition, few Twitter engineers engaged in "machine learning for advertising optimization" after the layoffs, according to people familiar with the matter.

Musk bought Twitter for $44 billion and served as Twitter CEO himself. Since taking over Twitter, drastic reforms have begun, and thousands of people have been laid off. Twitter also includes the suspension of office rent, and even revealed rumors that "employees bring their own toilet paper to work."
