if you need a job really bad then say that you have "open availability" depending on the department that they put you in (you can not choose) you would need to be able to work at least one weekend day. Also if you tell them you would like to have a "night shift" you are almost guaranteed to get the job ( it is really hard to get moved to day shift so make sure you know you can work those hours). During night shift you will be in the building with about 10 other agents max and the work load is really light, pack some good snacks and a good book and you will be fine .
