Each province's civil service exam is held on different dates.
Tips
culture
省考 selects civil servants for provincial and below-provincial government posts. Most provinces jointly hold a 联考 in spring, while a few (e.g. Beijing, Shanghai) run separately. Often cited as 'easier to pass than 国考' because posts are more numerous.
usage
Contrast pair: 国考 (central/national posts) vs 省考 (province-level posts). Many candidates sit both in one cycle.
