What is the best and most effective way to find a job?

First of all, we should seize the opportunity of campus recruitment. Enterprises participating in campus recruitment are much more formal than the units in the talent market. You can also try online recruitment. I'm looking for this job online now. Some big recruitment networks are not effective, but there are more opportunities in some places. Of course, having a friend introduce you to a good company will get twice the result with half the effort. It's hard to say which is more effective.
