Pros
ARGO has been growing very fast which presents a lot of opportunities for staff with the right skills and attitude. As ARGO is growing they have invested in HR and support functions to put more focus on giving employees benefits and support they need (including a considerable list of training classes). ARGO does a good job in recruiting talented people (rather than settling for warm bodies) and the culture respects people based on knowledge rather than on position / title.
Cons
ARGO has quite a few products that are built on proven but older technology that is in need of updating (the company has initiated a project to build a new architecture layer on .net but it will take time to develop the level of product sophistication necessary to replace existing infrastructure). People staffed in the Richardson office are generally expected to be in the office daily - so if work from home is important to you be sure you are interviewing for a work from home position which exist but are not the norm.
