Alibaba Group is a huge company, involving e-commerce, finance, cloud computing, artificial intelligence, entertainment and other fields. Therefore, it is relatively difficult to choose the most worthwhile department to work for, because each department has its own characteristics and advantages and disadvantages. However, the following are several relatively well-known and promising Alibaba departments for your reference:

1. Alibaba International Business Unit: Alibaba International Business Unit is responsible for promoting Alibaba Group's overseas markets and providing e-commerce platforms and cross-border trade services to global merchants. Alibaba International Business Unit relies on global talents, technology and resources, so it is very promising in internationalization.

2. Alibaba Cloud: Alibaba Cloud is a cloud computing brand under Alibaba Group, providing cloud servers, cloud storage, big data, artificial intelligence, Internet of Things and other cloud computing services. With the rapid development of the Internet and smart technology, cloud computing technology will also become an important field in the future.

3. Ant Financial: Ant Financial is a financial technology company under Alibaba, mainly providing financial solutions such as digital payment, wealth management, and credit services. Ant Financial is currently valued at over $300 billion and is one of the world's largest financial technology companies.

4. DingTalk: DingTalk is Alibaba's enterprise-level communication and collaborative office platform, which helps companies improve the efficiency of collaboration between employees and within the company through powerful online office tools. With the acceleration of remote work and digital transformation, DingTalk is also a very promising department in the future.

It should be noted that the choice of department should be determined according to one's own interests and professional background. At the same time, consider the employment environment in the city where you are located. For example, Hangzhou, where Alibaba's headquarters is located, also has many job opportunities.
