PSD interview

Got a call today whilst understudying Edmund for DO, PSD wants me to go down for an interview at 9am, Level 7, Treasury Building. This is one interview I really need to score for, after all, it's my 1st choice ministry. Anyway I have to go outfield come Wednesday. Still have no idea what my involvement is, do I have to dig shellscrape or wear helmet for example. Just know that the platoon training is in the Lim Chu Kang area. Shall deposit my fullpack and SBO in the store tonner tomorrow. I'm also DO tomrrow, my 1st DO in bn. Hope I don't screw up and sign many many extras.
