Pros
Work from home. If you're curious and communicative you may be rewarded - or at least recognized. High turnover means that if you stick around for over a year, you'll most likely be a "veteran". If you're savvy about the structure of the greater organization, play your cards right, and don't act too smart about it, you could go very far at this organization.
Cons
Constant power-plays by individuals less grounded in ethics than the average person working around healthcare. Becoming a soulless IT company now, with low diversity beyond certain levels. This is a white/male culture that is addicted to outsourcing and consistently demonstrates a "race to the bottom" greed-is-good ethos. Leaders shirk their responsibility to set and stick to SMART goals. Some VPs - I kid you not - have literacy challenges in their native language(s). The C-suite endorses monopolistic dynamics toward luring and capturing clients - despite this approach being at odds with marketing itself as a "trusted partner". Some teams do well enough to be featured in newsletters, but most technology teams are always behind and under-supported by the greater division, year after year. A lot of talk of innovation, but IQVIA will always just acquire the parts they think they need then struggle endlessly to integrate features into half-baked "IQVIA" solutions.. the goal of these acquisitions is really "grab & gut" as their revenue and reputation is used to support divisions that would otherwise fail, and the salaries of Presidents, VPs, and Sr. Directors who would otherwise have no revenue to justify their existence. 3-years post-merger and still dealing with Quintiles vs IMS culture, which is complicated by a never-ending influx of new characters with their own hubris and poor comprehension of IQVIA's greater corporate structure and operations.
