Pros
+ Everyone in the wet-lab (in particularly the different chemistry and biology team leads) seems passionate about their work and happy to explain the science to interested listeners, even those without a strong background in the relevant science. + Opportunity to learn about the different parts of the drug discovery process at a large pharma company in practice.
Cons
- Dry-lab R&D efforts seem to languish from a lack of clear criteria for adoption -- you're told to work on a thing, and it may or may not work, but even if it does it's unlikely to change how anyone does their work. - Little chance for mentorship unless you happen to have more of a team lead as your manager rather than a people manager. - Company gives very little incentive to keep you around -- seems to be OK with high turnover.
