The employment information management system of colleges and universities in the big data environment is built in order to efficiently manage the employment information of colleges and universities and improve the employment ratio of college graduates. Graduates may amend their personal information, comprehend employment-related information, and review recruiting data using the system's graduate management interface. To identify graduates who satisfy the employment criteria, businesses utilise the enterprise information management platform to create their own materials and distribute recruiting information. The platform for personalised recommendations employs the recommendation method based on historical user data to achieve offline employment recommendation and the recommendation method based on current user behaviour data to achieve online real-time employment recommendation and enhance the employment ratio. The platform for tracking and managing employment information is in charge of keeping track of graduates' job data and confirming the validity of recruiting data. When the number of concurrent users varies, the testing findings demonstrate that the system has a quick reaction time and a low resource occupancy rate. College graduates' likelihood of finding job has successfully increased.
