i think it depends on where u get, some departments are just bureaucracy over bureaucracy, manage vendor instead of doing real work. these are the jiak liao bee departments

on the other hand, some depts do real work, from user requirement, to prototyping, coding, testing, uat, sit, deployment, maintenance on an ongoing system, these however are the most siong critical infrastructure departments with very little work life balance. in these depts there are many things to learn, but not sure if one can take it with ongoing 24/7 support even when there is some form rotation

also promotion is very slow, typically 3 years once, grading almost like civil service, 2 years of grade "Bs" and fulfill some criteria then can promote.

If u want a fast career track, don't join, u will feel very slow inside
