Pros
It is very challenging environment, a lot of codes need to be implemented fast and deployed fast to meet customer needs. The whole company is very customer obsessed and always ready to respond to customers as highest priority. It is a great place where you can learn a lot in a short period of time. When you need helps, a lot of people, a lot of departments are willing to help you get things through. Most of the people are smart and super diligent. My manager probably only sleep for 4-5 hours and constantly working everywhere.
Kontras
All condemnation to work life balance is wrong, because there is NO LIFE at all. After a 1.5 months of working 12 hours a day, 6 days a week to meet a hard deadline without payroll for extra hours, now the consolation is I can work at home on Sundays or on weekday nights till 11pm after I leave work at about 6. Although, my manager work even longer and my colleagues are similar.
