Do an advanced search on my user name and Somnia and you can see what my experience was when I was considering a job with them.
Go over the contract with a fine tooth comb.  I am not the only one who they told that there is no non-compete in the contract only to later find out that, in fact, there really was a non-compete in the contract.  When I pointed it out, they acted very surprised and stated that must be a very recent change.  They gave the same song and dance to a friend of mine a couple of months later. 
You will almost certainly work a lot more call and a lot more late shifts than they promise.  The schedule that they promise is based on a full complement of anesthesiologists.  They never have a full complement of anesthesiologists.
