The report also revealed that the global hiring activity (posted jobs) continued to decline by 15 per cent year-over-year (YoY) and 6 per cent quarter-on-quarter (QoQ) in Q2 2023. However, the Middle East and Africa, South and Central America experienced an increase in job postings. On the other hand, countries with notable growth in new jobs include Japan, Czech Republic and Brazil. "In terms of themes, e-Commerce, Social Media, Edtech, and 3D Printing were the other notable themes with higher job postings," the report said. The launch of Generative AI tools like ChatGPT and Bard led to a substantial increase in AI-related job opportunities. 'A remarkable 106 per cent YoY growth in roles with exposure to Enterprise Social Networking and Collaboration Platforms serves as an example supporting the adoption of these technologies," explained Sherla Sriprada, Business Fundamentals Analyst at GlobalData. /IANS
