Kontras
1) First few months can be a bit of challenge for new folks to adjust Amazon's culture and peculiar methods. 2) At times the work load can get overwhelming especially when there is customer impact, but this is again not by design but teams failing to do the right things. Everyone is empowered to to the right thing and make improvements.
