My experience- YMMV. Be careful who you talk to and what gossip you engage in. Basically everyone knows everyone to some degree. Everybody is somebodies cousins friend or something. Its a good thing when you get used to it, more security and whatever, but it does mean that any social damage you do (cheating on someone for instance) will have far wider consequences than you realise.

Job hunting is extremely difficult for the same reason unless you’re trained in some in-demand specialist skill. Every job goes to someone’s cousin. In my last factory job we had an idiot working there, constantly on the verge of getting sacked, he attended a funeral one day and discovered that his dead cousin was also cousins with the manager. He was team leader the very next week for his overall diligence to duty.
