Based on big data analysis, the longer users use it, the more they can calculate the positions and salary ranges that users are interested in, and intelligently recommend and match the positions that students are interested in, thus improving recruitment efficiency. Based on the product experience, student certification and student insurance will be launched soon. Strictly review the enterprises that have settled in. Once a student is cheated into taking a part-time job, the certified enterprise will compensate 10 times the salary insurance amount. After students improve their resumes, they can submit them to the enterprise with one click. Enterprises can view students' resumes and give feedback like a hook, so that students' resumes will not sink into the sea after delivery. Anonymous part-time student community will be opened soon, which can share all kinds of practical information and make friends, and increase user stickiness and use time through anonymous community platform.
