On the bright side: large projects are generally full-process supervision, and there are many things to learn, but the key is whether to learn or not. Personally, I feel more tired than the construction unit, so I can study in my spare time, and I can take an examination of construction engineer, supervision engineer, cost engineer, intermediate title engineer, structural engineer, etc. This is also the reason why many people enter the supervision unit.
Disadvantages: China's supervision industry is not very mature, and it is not as good as foreign countries. In most cases, supervision is just a decoration, and sometimes the owner doesn't want you to care too much. If nothing is done, supervision will definitely intervene. Furthermore, if you are not a savvy person, you can only learn a little in the supervision industry, which is not conducive to future work. And the supervision industry earns less.
I am not necessarily an insider, but I am an insider, and I think I have answered your question objectively. I hope to adopt it ~
