you talking about fresh grad salary or mid career?

fresh grad one should be competitive. but dont compare to tech companies of course.

but mid-career cfm very average. many will take pay cut if want to join.

but yes, every 3-4 years will revise salary. 2015 got once. 2019 I think got 6-10%. 2022 got one more, but joke. I think only 2% or so. i personally feel the dept reviewing salary dont have the accurate feel of outside salary. mindef used to be quite competitive but recent years have been very below outside.
