Pros
The workplace culture is very respectful of the individual, and the marketing department in particular highly values the need for work/life balance. This is very rare in the A-E industry, where burnout for marketing/proposal staff is common. The salary and benefits are very competitive (I would even say generous compared to other firms I've worked at) and they even offer overtime for staff making less than $90K. And there are lots options for career advancement for entry level and junior professionals (up to a point, see cons below).
Kontras
The marketing department can be a little too rigid in their processes, with systems and processes developed and put in place based on what works in the headquarters office in New York. This doesn't always work well in practice for other offices that don't have the same staff or resources as HQ does. Options are also limited for advancing into a regional or departmental management/director position, but only because everyone likes working at STV so much that there isn't a lot of turnover at those upper management levels.
