There is no training before entering the job, and only half a month of full-time training after one year. Generally, all cities and States conduct training in local party schools in a unified way. As for accommodation, it is generally the guest house of the party school, and the conditions may vary from place to place. But there is no need for uniform accommodation. You can decide for yourself. During the general training period, the unit will give you a training allowance. Each of us will pay 2000 yuan this year. Of course, you have to fight for it yourself. The more people in general units attend the training, the better. If you are alone, it may be a bit difficult.
I hope my answer will satisfy you.
