Business process improvements are sought on a consistent basis in any industry and the banking industry is now exception. And because many of these process changes are initiated by frontline employees like Tellers, your interviewer is looking to hear that you will always have an open eye toward seeing improvements. As you answer this question, while there is no right or wrong answer, use a methodical approach in answering how you would approach this situation hypothetically. If you have a time that you did just this, be sure to explain that to your interviewer as well and walk through your thought process in that situation.
