Pros
A lot of different testing to learn, if management will allow you to crosstrain.
Cons
Relentless micromanaging of tasks. Lunch breaks are short and monitored/micromanaged. You get hassled for trying to take a regular 15 min break. Management will only choose a few people per department to crosstrain in all testing for your department, so if they don't like you, then you're out of luck until they're desperate. There is a lot of backstabbing and gossip between coworkers because it's a huge competition for promotions and training. The environment at Nelson Labs was one of the most toxic that I have ever encountered. I only recommend starting here to get as much training as possible in 1 year and getting out as quickly as possible. Cars get broken into a lot as well.
