What is the treatment of graduate students in Nanjing Electromechanical Hydraulic Engineering Research Center (including welfare, year-end bonus, etc. )?

Today, their recruiter explained to me in detail the composition of their treatment, the first year's salary plus bonus, 4,500 yuan per month before tax. Then it will rise every year, by 10%~30%. There is a monthly housing allowance in 400 yuan for five years, and one room for two people is paid to 400 yuan every month. Housing accumulation fund 12%, sum of three risks 1 1%. In the past, mechanical graduate students were guaranteed to become senior engineers within seven years, and they could apply for researchers after eleven to twelve years. A concrete example-graduate students who graduated in 2006 have a minimum salary of 7,000 yuan and a maximum salary of over 10,000 yuan five years later. Now they have more than 800 employees and more than 80 graduate students.
