Planning on joining the army and going into Delayed Entry for seven months. What is DEP like?

I am in the process of joining the army and I will likely be going into the Delayed Entry program for several months. What kind of stuff happens during delayed entry program. Does the army do further investigation on you and have you do more meps physicals or do they just let you hang for a while. Is it possible that they may have you do some extra PT tests. Can delayed entry help you with your job search in the army and make it easier to get the job that you want? What are the advantages and disadvantages of DEP?
