    What worried 22-year-old Shanghai graduate Tang Yining the most until mid-March was uncertainty over finding her dream job as soon as the COVID-19 pandemic ends.

A few job interviews originally scheduled to be held after the Spring Festival holiday were all postponed due to the outbreak-related restrictions on free movement of people.

Thankfully, three interviews were shifted to the online medium. "They are actually more efficient than I had expected. In fact, online interviews helped me save time and money because for offline interviews I usually end up traveling to different provinces," a college graduate said.

According to online recruitment(招聘) firm Boss Zhipin, the number of companies using distance interviews increased by more than 20 times within 10 days after Spring Festival, compared to the first week of the autumn recruitment season in 2019.

Industry insiders said online recruitment will help fill in job vacancies in time and is of great significance to keep the employment stable nationwide and further offer economic impetus（推动力）.

“Public employment service agencies and the market players concerned should also be encouraged to share information on job vacancies and strengthen the coordination of online and offline recruitment activities to ensure a stable job market,”Chinese Vice-Premier Hu Chunhua said.

As of mid-March, more than 50,000 companies had participated in the online campus recruitment, providing more than 200,000 positions.

Over 450,000 university students on the verge of their graduation had made 1,700,000 job application submissions by then, said online recruitment platform Zhaopin.
