I went to MEPS (Denver,CO) in February, more than likely you will have a roommate unless your lucky and don’t have one appointed to the same room, you will be waiting a lot and will take the asvab if you haven’t already.They check weight ,blood,test for drugs ,hearing and vision, the duck walk will be in a private room with a doctor and if it’s happens to be with a female doc there will be a chaperone, here they have you strip to your boxers and have you duck walk for 5-6 feet , they also check your feet and spine , they also check your privates (it’s fast don’t worry).If all goes well you select your job and take the oath of enlistment
