Whatever you do don't say that you are unable to work in a very structured job. Chase is really big on structure and knowing your role. Tell them that you love helping people and that sometimes you might be too invested in your clients success but just need to learn to trust your team members who you hand them off too. For example, the PB will hand off clients to specialist who need help with investments, mortgage, car loans, etc.

Don't give a transparent answer like "my strong personality to be the best." Give a REAL weakness, and then show how knowing it's a weakness helps you to be successful.
