Pros

Great for starting in the industry and getting your foot in the door.

Cons

Environment is toxic. SOPs are a mess. Many corners are cut and grey areas cause conflict within teams. No one gets held accountable. Moving up solely dependent on having a good enough manager to "sell you" for a promotion and the pay doesn't move very well, bonuses included.
