Company-wide policies such as benefits, bonuses, different type of leaves and exercise, team-building stuffs are pretty good as per any big organisation. Culture generally amicable. Processes generally bureaucratic but not as much as actual govt org,
There are many sub-cultures even within 1 department as it can be as huge as a SME. Actual culture depends on team lead, so people who does the interview may be the ones who set the 'culture' in the team.
Most management are trying hard to do employee engagement, of course there will be some that just let time pass by.
