Pros
Historically, they reliably delivered payroll and expense reimbursements on schedule. The approach of new managment in 2012 seems to be to hire young, inexperienced, highly trainable people with low salary expectations, which presents a great opportunity for someone early in their career to get some good software industry training and experience.
Cons
I had limited experience under the new management regime, so my perception may not be applicable over the long haul, but their frequently-mentioned, but not shared, 'Vista Equity Partners standard operating procedures' seem to include management direction to not develop relationships with underlings because you never know when they will fall on the wrong side of the bell curve and be laid off, so better not to get emotionally attached. Management strictly by the numbers. Makes for a passion-less, sterile environment.
