It is particularly effective if you have an interview scheduled in an area where there are a few other employers of interest. Visit their personnel offices. Inquire about open positions. Pick up an application to take home to type. Wait to see a recruiter if possible.
Some organizations have specific days for drop-ins at the personnel office.
Applying to Jobs that Are Open Check the Sunday edition of the newspaper. Subscribe to the newsletters and journals of the professional associations in the field. Check Internet listings. If you have a friend in an organization you're interested in, have him or her relay to you the internal job openings bulletin. Frequently, organizations publish openings for internal applications a week or two before they release them to the general public.
