Job searching in challenging times

Firms seem to be very cautious in their hiring. They want top performers that create value many times their cost [wages + benefits]. They always do. But now, the time from the first job post to hire seems longer than usual.

Some of the tools being used in my search...

1. http://www.indeed.com/

2. http://www.oodle.com/job/

3. http://www.careerbuilder.com/

What are some job search sources you use or have used in the past?
