Why is it so difficult to find a job in the supervision profession now? I haven't found it yet.

Garbage industry.

The management of many supervision companies is irregular. It means that several directors work together and then each do their own work. If you want people, you can just drag a few of them in the talent market.

Because supervision does not have high requirements for personnel, there are not many people recruiting online. I suggest you visit the talent market more often, maybe you will find one.

But this business is really rubbish, so I’d better switch to construction.
