Yes, I did attend Sheffield. At the time, they only offered the full-length course. They still recommend that one but they do offer some shorter options now.
I got a job with a regional airline in New England about three months after I graduated (was a bit of a challenge to get interviews with no experience, but I persevered) and after a little over a year there, I got a job with a different regional in the Southwest, which is where I'm from. (I probably would have stayed longer, but the carrier that first hired me, Business Express, was in Chapter 11 when I left.) After a few years at that second regional, I left to work at a startup called National Airlines based in Las Vegas. One of my former bosses was managing the SOC department. Anyhow, I enjoyed National, but higher oil prices combined with 9/11 ultimately proved fatal to their business model, and I was looking for work again in late 2002. I found a new job fairly quickly, though, at a regional based in the Midwest, and I worked there for about three years before finally getting hired by a major a couple years ago.
My trip to the majors was probably longer than it could have been, and 9/11 definitely didn't help anything. However, I was quite happy at National, and had they stayed in business, I doubt I'd have left there. Such is the way of aviation. I am living proof that if you persevere, though, you can get to a major. Some people in my class here had a lot less experience than I did, too.
Wherever you ultimately get your license, good luck on your career! I do think that Sheffield is a good school, but remember that any license is a "license to learn."
