Pros
good colleagues
friendly environment
good benefits ( medical insurance, grocery subsidy, stock market share)
job security
nice working office ( + coffee and vending machines, lunch)
Cons
1- micro-management
2- weak HR ( HR? No - Threatening Department? Yes)
3- managers love rumours and office tea instead of employees' performance :D So, there are not fair and reasonable chances of promotions and raises, especially for older employees.
