Pros
I've been in banking for nearly 30 years and of all the different financial institutions I've work at; First Internet has created the best workplace culture I've experienced with everything from a casual dress code, free snacks and refreshments, to fun activities that build teamwork. The IT team is the most responsive of all the IT departments I've worked with, and managers and HR follow up with employees to make sure they have the tools they need to succeed. First IB has a successful entrepreneurial CEO who has assembled a competent senior management team that continually fosters an innovative and positive work environment. The fast growth of this bank also creates opportunities for personal and professional development.
Cons
I've not yet experienced any noteworthy cons.
