I applied in-person. The process took 4 days. I interviewed at Garvin County Sheriff (Pauls Valley, OK) in Jan 2013
Interview
The Undersheriff will talk to you very briefly, introduce you to the sheriff, give you a tour of the jail and let you set in on a day time setting. You are then required to tell them of any other jobs you currently hold and when you will be able to start. It was a very short and quick interview.
