New member, so trying to get my posts made. I can contribute to this!
I spent a couple of years as an instructor for FlightSafety. My interview, which may not echo others' experience, was very laid back and friendly. They did a nice job at putting us at ease. "Us" was me and one other guy. We did the entire interview together, up until the presentation, which we did not observe each other's. One thing to note: they gave us some material before the interview which would describe what would take place and what was expected of us, particularly in the presentation.
Dress: we each wore a suit and tie.
It began with the HR guy giving us a tour of the facility and a general overview of what to expect. There were a few questions here or there, but nothing remotely overwhelming...just a get-to-know-you feel. Once that was over, we were led to a room where the Center Manager, Assistant Manager, Dir of Standards, a couple of seasoned instructors, and many others that I don't recall their titles, were all seated in. We all had lunch (sub sandwiches) and just talked and joked - they wanted to get to know us. We were asked various questions, like "Why FlightSafety? If you couldn't fly/instruct, what job would you want to do?" and what not, but everyone went around the room asking various questions and taking turns answering. It didn't feel like an interview at all and was actually a lot of fun.
What came next was, what I thought, really pretty neat. They put the two of us alone in a room with the two veteran instructors and told us it was, basically, not rigged or staged in anyway, and that once they (management) left and the door closed, whatever was asked was between the four of us. They let us just pick the brains of those two guys, and get the good and bad of working there. After that we were each split up and we gave our 15 minute presentations. The presentations were given in one of the classrooms, and in front of pretty much all management/Program Managers, and some instructors. A few questions about the presentation were asked at the end, but mostly really softball stuff just to see how you respond.
The presentation could be on anything aviation related, and you would best use PowerPoint, although it wasn't "required." I've heard some Centers allow you to present on anything, meaning it didn't have to be aviation related. I chose to present the Fuel System on a jet I had been flying, knew well, and was one that they did NOT teach at that facility. (Don't select something to teach on if you think you might have some experts in the audience...i.e. don't teach how to make a tire to the Goodyear factory guys.) They are not looking for "what" you teach, but rather "how" you teach it. Time yourself. Then time yourself ten more times. Present the topic to your wife or friends. Ask questions and INCLUDE your audience - facilitation!! Use humor, but not much. Did I mention time yourself? Don't go under, and don't go over. You need to teach in the allotted time.
One question that was asked during the informal lunch, which I wanted to mention in greater detail, was "Are you done flying? If American calls you tomorrow, what would you do?" I was coming from an abusive 91k/135 business with horrible QOL, so I was very adamant that I needed to be home for my wife and young kids/infant. I had had enough of the road warrior stuff and needed stability. He went on to explain that they did not allow any outside flying. Period. He emphasized that a lot. I heard rumors later on that there was some incident with a FlightSafety instructor in the right seat of a plane he wasn't rated in, just riding along, but because there was an instructor in there, they came after FlightSafety. Don't know if it's truth or what, but it was made very clear to us that we were not allowed to fly at all. We could rent a C172 on our own, but that was pretty much it.
I thought that was FlightSafety policy company-wide, but I learned later on of instructors at other Centers being able to do contract stuff, which irritated me a bit. I very well may have stayed if we were allowed to fly here-and-there. As a result, I got pretty burned out and left for a flying job, however, I really did enjoy my experience there. It's up to YOU to keep it entertaining! If you use the same airports, same scenario, same thing over and over, you'll go crazy. Keep it interesting and come up with new stuff all the time. (I realize this is an interview experience thread, but wanted to convey my overall thoughts.)
Hope it helps!
