I'm a teller at a bank, it's very interesting dealing with lots of customers.
Must be a great job interacting with them. Did you have to get special training to be a teller?
I received on-the-job training when I first started.
Do you work for a big bank?
I do, I work for Bank of America.
What does your job entail? 
I mostly interact with customers and provide them with information about their accounts.
