Pros
Citizens was once a strong community bank and its best asset were the people. This is still the case - although there are very few of them left.
Cons
All of benefits have been stripped down to bare bones. HR "spins" that these cuts are to make the company competitive. The salaries are far below marketplace and if you are interviewing make sure to ask about the percentage they have paid out the bonuses over the last few years. Over the past few years this has become a really sad place to work. It is unfortunate as there are some good people still there but most of the people who are ambitious and A Players have left. If you are interviewing be very wary and make sure you probe on the morale and leadership of the department you are joining.
