Lots of opportunities, lots of silos
Pros
IQVIA is the undisputed leader in healthcare data; the client base is massive and includes both household names and lesser-known pharmaceutical companies. Some of the work is fantastically interesting, and there are seemingly unlimited opportunities for career progression; it depends on the group, but my group is very supportive of opportunities to grow one's career, whether internally (within the group, internally (within IQVIA) or externally. The business is well-run and growing (both organically and acquisitively). On the work-life balance and compensation fronts, IQVIA is good. I have complete flexibility to work remotely whenever needed and to work the hours that are convenient for my family. The total compensation package is excellent, especially given my title. 401k matches dollar for dollar up to 3% and 50 cents on the dollar up to 6%; benefits package (except health insurance) is great.
Cons
The company is very siloed; I work in a small group and have essentially no interaction with the other groups. Health insurance options are not great; though premium is inexpensive, coverage leaves room to be desired. The company under-titles its mid-level consultants. Compared to the Big 4, the IQVIA consultant title translates to senior consultant; senior consultant translates to manager; engagement manager translates to senior manager. This is truly an applicable comparison in both responsibility and compensation, which means that you will need to explain your title if you seek employment elsewhere in the consulting world. The culture is a little "meh" - It is certainly not toxic, but there's no real camaraderie or anything like that. They moved to "unlimited PTO", which is nice in theory, but in practice I expect that fewer vacation days will be taken. The move to unlimited also removes financial liabilities from their books since they no longer have unused PTO to compensate. Smart fiscal move, but I'm not a fan of the policy in general.
