I went on the subject interview two years ago when I was at the 4 year mark of my current employer. The reason I was looking is because my current employer was being acquired and all of us received a letter stating, "We will tell you in x months whether you have a job or not." It turned out about 80% of my coworkers got laid off but I did not. But I didn't know it was going to turn out that way at the time.
I'm not interviewing now, but honestly they're just trying to figure out a way to cut me out of the picture without torpedoing the business I support. Eventually they'll find a way though realistically it's another year away. I have one fall back company I can go to in a snap at equal pay and I do side consulting about 15-20 hours per week so I'm not worried enough at this point to be interviewing.
