i see bnf i know you are
ntu alr.
mas starting is 3.6k and yes big 4 increment is bigger
mas is prestigious but still lots of red tape. there is no MA programme. everyone is a GO (graduate officer) so it's merit-based, no flashy titles.
culture depends on which team you're in (supervisory, transformation, policy etc), but definitely not as dynamic as private sector.
would say
mas is a good balance between govt ministry and mnc, in terms of welfare, benefits, stability, but very boring culture and can be political. definitely less competitive than banks but one of the better tier stat boards.
they accept up to 30 GOs. it's on their website. first round group interview/assessment, then interview with management. that's all.
one last note, the hr is quite bad. they are super slow and unresponsive, and say they are proceeding with your application but 3 months no news (after completing first round). many of my friends were stuck for 2 months before hr got back to them for the next round. by then most of us already found jobs in better institutions.
