Pros
Put the work in and you get rewarded via grouping. Life is easier if you can maintain QA to 100% however if you fall into group 2-3 then scheduling becomes limited and the margins are extremely small. Some projects you can do the bare minimum, it's a quiet hour if you work UK mornings aka GMT-8 shifts. It's sink or swim with less than basic training over the course of every project, Project managers are terrible except for some outliers who go above and beyond but within 5 years I experienced 2 out of 15+
Cons
Unless you're perfect then you will be fighting for hours based on internet connection, Scheduling is absolute atrocious and they never got it down properly in 6+ years. On Christmas time they have false incentives such amazon giftcards for hitting targets however it's a battle back and fourth with management for them to follow through with paying the bonus. You are cattle and a test to management, they will test you like a guinea pig. You need to swim and never sink.
