Ventajas
The institution has a lot of resources (finance, manpower) to carry out projects, but the projects are slow and there are many rules to follow, many egos of internal stakeholders to massage, and deference to senior management. Great benefits if you have many children - free education benefits (which is needed since they have to attend private schools).
Desventajas
Manila is a horrible city - think twice before coming. There may be pockets of "Singapore" but the rest of the city is not great. It is depressing seeing the slums, while being stuck in traffic. And you have to deal with typhoons and earthquakes. The institutions has many rules and they follow it, even it does not make sense. Things can be more efficient but they would rather stick the rules, because it is easier to do so. No one takes responsibility. There is such deference to senior management, and adherence to hierarchy. People are addressed as DG, VP, etc. The quality of manager is mediocre. Manager is focused on fulfilling the requests of senior management and less on the quality of work from staff. But you see that they are not penalized for this, but rewarded. The average quality of staff is low as it is difficult to attract and retain the good people in Manila. It is then not motivating to be working in the team.
