This is from my own experience working at a TP call center, for a major tech client and not in Albania or Colombia.

External and internal audits are known for weeks in advance such that they could put a facade on in time. During audits you suddenly don't have a limit on bathroom break time (generally an alert would come at 15mins per day) and there would be pizza at the office every other day. Only 'loyal' employees would be chosen to any interviews/meetings about culture etc.
