And remember:
This isn't Mcdonalds where you go in and get a Big Mac and get out right away. You have a long list of forms to fill out and wait for them to be verified, along with your testing, both mental, medical and physical. Then, of course, you have to have an opening in a Trade that you wish to enter. If there are no openings, then you will have to wait.
Further research into "Wait Times" and "Trades that are Closed" may help you to realize what to expect. This calls for one of the most important qualities that the CF is looking for; initiative.
