I think most new hires are getting DTW and FLL. DFW and LAS are going senior, but this is all relative. You're not going to be waiting years to get any base as a FO, maybe a few months.
Congrats on getting hired, I'll echo Wisconsin's sentiments, if you can study prior to coming down for training, the better off you'll be. Personally, I concentrated on Limitations and Memory Items, Checklist responses and Controls and Indicators.
For our military guys, congrats on getting hired, Memory Items aren't Boldface, it took me awhile to figure that out.
