Hi there, I applied in late January. Was asked to send in further documents in late February and then had to complete an essay test within 24 hours in late March. In late April, they invited me to an interview, which I went for in the first week of May. After that things moved very quickly. Received a shortlist notification within two days and went for a second interview that same week Friday. The following Monday they notified me of my unit preview, which I went for last Friday. Am waiting for HR to give me a verbal offer now, but the wait is making me nervous haha.

This timeline was for the office I applied for at least; not sure how those of other positions might be different. From what I have gathered in this forum, each office within MINDEF has its own hiring timelines.
