Where is the Beijing Jinggang subway interview job fair?

Interview job fair? I don't know what you are talking about.

If you are informed of this interview after taking the written test, the interview place is: the administrative office building of Beijing Jinggang Metro Company Headquarters, Jiayuan Road, Fengtai District, Beijing (take Line 4 to Exit D of Gongyi Xiqiao Station, walk 590 meters south to the intersection, turn west, then go straight for 300 meters to the T-junction, turn north and walk 50 meters, walk to the intersection where buses enter and exit, and walk into the Jinggang subway compound).
