welcome. are you shortlisted for tengah airbase? logistics? basically it differs from camps to camps. some hiring managers, i.e the COs , would invite a few candidates to visit the site. then they will further shortlist. basically is just walking around the unit, meeting people you will get to work with. they might give you a brief intro about the operations of the unit.

for my case, i was the only one shortlisted. so basically it was just for me to decide whether i was ok with the location/workplace. my advice to you is to be direct in any burning questions you might want to ask. like asking if you are their first choice etc. dont leave yourself hanging.

if successful, they will contact HR and they will arrange medical for you. usually at most 1 day after your CO tells HR they want to hire you.
