Heard about job through college advisor, but they will also post on job boards and craigslist. Emailed resume and cover letter to head of GIS department, was sent a personality test of sorts that I took online. Interview took place at office; I took a "GIS test" to prove I had knowledge of basic ArcGIS functions. Was told I was not a suitable candidate at the time via email, but then was called back a few weeks later and offered the job.
