I'm a bank teller but the work os so boring
Do most banks provide on the job training, 
Yes they ensure you keep up with new information and only certain jobs require college education
Tellers also have to be friendly and interact a lot with the customers .
Yeah, there's all types of people that come in there. Do you know much about the job?
Just what I've read. In the U.S. tellers held about 608,000 jobs in 2006.
Wow I had no idea there were so many
held approximately 608,000 jobs in 2006. Of these, 1 out of 4 worked part-time. Median annual earnings as of May 2006 were $22,140.
The number of tellers in the United States increased from approximately 300,000 in 1970 to approximately 600,000 in 2010. Counter-intuitively, a contributing factor may be the introduction of automated teller machines. ATMs let a branch operate with fewer tellers, making it cheaper for banks to open more branches. This likely resulted in more tellers being hired to handle non-automated tasks
Bank teller
A bank teller (often abbreviated to simply teller) is an employee of a bank who deals directly with customers. In some places, this employee is known as a cashier or customer representative. Most teller jobs require experience with handling cash and a high school diploma. Most banks provide on-the-job training.
Tellers are considered a "front line" in the banking business because they are typically the first people a customer sees at the bank.
