There are many ways to get a job. Duh, we all know that. Of course it's important to have a good resume, do well in an interview, and get an education, but networking will get you places you never dreamed of.
Think of it this way: If you send in an outstanding resume to a company of your choice, but someone else whose resume isn't quite as good as yours knows the person doing the hiring, who do you think will get the job? Probably not you. But what would have happened if you would have done some networking beforehand and gotten to know the person doing the interview? Maybe your resume would have mattered then.
So, it's not that a resume isn't important, it's just that you may need to take some necessary steps to make it important.
You have to know how to network, though, which is why the following link is important to read.
