I chanced upon this thread and empathize with those who are eager to know the outcome of their interviews.
Normally they will reject you quickly if you failed your interview.
if you had to wait, it is likely you were KIVed (good but not best), or they are putting your name for management's approval.
HR is known to jam certain offers even when line PCs decided to offer their candidate, for reasons unknown to me.
Those KIV ones may eventually be offered / rejected especially if new resumes were received (if you noticed, some job applications on the career portal do not have application end dates).
DSTA is predominantly engineering, with most departments doing PM / Systems Management. Therefore you are required to have project management and engineering knowledge. Engineering knowledge is important (so said our top govt ministers) and can be transferred to places like
LTA,
SMRT,
PUB.
But
DSTA also have Computer science folks doing Cybersecurity, SW development, QA, QC etc. These skills are very transferable but likely to be lowered paid if you wish to venture into Pte sectors.
Pay, welfare are good, depending on which sector you compare to (prob. not as good as oil/gas, banking. But definitely better than IT industry)
All the best folks.
