As a Teller with Canadian Western Bank, solid data entry skills will help ensure that you are able to handle customers in a timely manner while also ensuring accuracy with each transaction that you process. While you may not have direct experience with banking specific software and data entry into those programs, your interviewer knows that skills you have built elsewhere can easily transition here to this role with ease. Talk about the experience you have with data entry in any previous positions that you've held. Talk about specific program that you have experience with and remind your interviewer that you are very easily trainable on new systems. If you know your words per minute typing skills, now is a good time to bring that up as well.
