Pros
SVB definitely has a strong client service orientation; for the most part, employees seek to do the right things to improve the client experience. The bank, while growing fast, is still small enough for someone to meet professionals across all functions and get good exposure with CEO and the Steering Committee.
Cons
While the company has brought in a lot of experienced technical and mid-management staff in the past few years to help scale the business, there are still some "home grown" managers who have not been able to keep pace with the business. CEO is commonly regarded as aloof, or indifferent -- I don't think that is true... I think he genuinely cares about the staff and culture at SVB. However, he is very deferential to his direct reports in operations and IT, to the point where it looks like he is abdicating responsibility -- it would be nice to see him lead with a vision across all functions.
