Pros
Compressed schedule, four day work week, or 4-1/2 day week (4 hrs on Fridays). When covid hit they very quickly pivoted to making bulk vaccine APIs, very impressive to see happen.
Cons
Four-day workweek can be thrown out the window on a whim so don't plan your life around it. Pay not at same level at the big players J&J, GSK, etc. Above average amount of nepotism. HR (in particular) and admin depts can be frustrating to deal with. Some, but not all, low-level and mid-level supervisors/managers exhibit imposter syndrome. To an extreme. The behavior is they will say/do anything to avoid even slightest hits or appearance of subordinates/new hires/outsiders knowing more than they themselves do. You can expect it to affect your pay, career advancement, work assignments, working relationships, etc., etc., it permeated everything. The managers above those who practice this annoying behavior seem to know it happens but do nothing to course correct, makes you question if they actually agree with it and concur with it.
