WAKE UP CALL!
At 0500 sharp, you will get an automated wake up call. You need to be in the lobby with everything at 0515. You will get a buffet-style breakfast until 0545. You will then load the bus and travel from the hotel to the station.
hurry up and wait
After a while, some important people will show up and you get to go inside. One of the most important things at MEPS is to listen carefully and do everything exactly as they say. After the security screening, you put everything away in a secure room and speak to your service Liaisons. They will give you a packet containing medical records and other medical paper work to be filled out. Then comes more waiting. You will hear "Hurry up and wait" too often.
This lasts for about 2 hours, and all you do is slowly fill out your paper work while sipping water. Sleeping is absolutely not allowed. If you are caught sleeping, you will have to stand in the back of the room until it is over.
The medical portion of the day lasts around 4 hours. You will go through a thorough physical, as well as other tests including urinalysis, blood test, eyesight, hearing, joint movement, and potentially voice.
Your recruiter will likely tell you that the staff at MEPS is trying to disqualify you. The doctors and staff say the exact opposite. Personally, I wouldn't risk lying.
Congratulation! You've made it through medical. Now it is time to select your job. Based on your ASVAB score and potentially other tests, you will qualify for different jobs. Some fields might not be open at the time, or there might not be any jobs available at all. If that happens, then they might put you into a filler job and switch you at a later time, or you will go back up again at a later date.
