Pros

You can get massages every month, there’s events. Also depends on who you’re team leads is and co-workers. It’s great when everyone works together as a team

Cons

Too much work in the mice room they sent me to. The team lead is horrible and put all the work and strain on me, and expect me to get it right within a month
