When searching for job opportunities, I go online and look in employment websites. With the advent of the internet, searching for jobs online is a popular and more convenient approach. You can even submit your applications online, too.
Each state has its local employment websites also. When I was in Hawaii, I utilized Honolulu County's website to look for government employment opportunities. In Florida, they also have websites for state, county or private job opportunities. For those in Philadelphia and the neighboring states, one can also find philadelphia job listings online.
