I had a interview for mc Donald's yesterday and she told me to bring in my state ID social security school ID and birth certificate and they copied it and told me info about the job... Does this mean I have the job

No, it's means you had an interview, and they're considering you for the job.

No, you have a job, when they tell you, to report on a certain day to go to work,

This was a interview to meet you, and make sure you had all the proper documents to work
