First of all, it should be said that most people get their jobs through networking, not internet or classified searching. Many jobs go unpublished or unadvertised, so while the internet is a great resource for the job seeker, it should be only one of the many things that you are doing to find employment. Most of your time should be spent talking to people in the FLESH, not surfing the net.
As you might already know, there are websites that help you look for jobs in certain fields like nonprofit, science and sales. If you type in “nonprofit jobs” in Google, you will find these fairly easily.
