Yeah, From 5 years ago, but I have heard that there hasn't been much change. Of course it will depend on the type of position you applied for also.
Fixed wing expect a C-210 ride, rotowing expect an A-Star and if you are dual rated expect to fly both.
All real straight forward stuff. Log book check, oral, personal interview, flight.
Oral; FAR's/Aim, general Aviation knowledge, just making sure you are who you say you are and that your log book matches your experience.
Personal interview when I went through was a panel of 3. They just want a feel of who you are and why you are interested. Similar to a panel interview for most higher end aviation jobs. Tell us about something dumb you did in an airplane. What is your greatest accomplishment. What questions do you have on and on.
Flight; VFR and IFR procedures, steep turns, stalls, Hood time, climbing and descending S-turns, practice appchs.
I am fixed wing only so I don't know the baseline for rotowing. I would assume you just do what is natural to do for the position you applied for. Throw in autos and hovering.
Oh yeah... don't worry if they don't let you land the 210. It is standard for the instructor to land it as they put a lot of wear and tear on the airframe during interviews a bunch of years back and stopped letting interviewees land the thing.
They aren't looking for a Yeager or a Hoover. So if you make a mistake correct it and fess up. They are down to earth guys at the school house (mostly) and are interested in finding someone who's experience matches what they put on the resume and that they wouldn't mind spending a couple of weeks with during a TDY.
Best of luck
