I agree + disagree. The numbers here seem to indicate that friends, recruiters, family, colleagues (i.e. important forms of networking) are an important part of the process.

Buuuuuut, look at those numbers for the importance of old-fashioned job listings. To neglect job listings (and to neglect traditional applications - with resumes, cover letters, and similar) would seem to be a mistake.

It is also interesting to note that "networking" (friends, recruiters, family, colleagues) seem to be more important for mid- and later-career professionals while online job postings are more important for younger career professionals.

There are differences by gender too. Women seem to benefit more from online job postings than men - while most of the networking strategies seem to benefit men more. So that is important to keep in mind when you have goals related to reducing discrimination.

I looked at your book. Looks like a great resource. I'm going to add it to my library. Thanks for sharing.

Finally here is an additional read I hope folks will find useful on this topic too:
