I worked at Savvis full-time (More than 10 years)
Great company that encouraged innovation and took great care of employees.
Savvis was acquired in 2011 and subsumed into the parent company in 2015.
Advice to Management
I applied through a recruiter. The process took 1+ week. I interviewed at Savvis.
Initial interview with about 5 developers who tried to get a feel for technical experience and team fit. Then interviewed with the team manager for more general questions.
