I'm also in the same situation like u.
Served ns in spf for 2 yrs and only hab ntc2 cert..
Went for the police selection last sept and panel interview last
jan.
They told me tat I will be joining the intake on march soon.
As for the interview part , u need to be well prepare 1st.
Talk with confident and try to know more abt the policing work
and shift hours.
When u are speaking to the interviewer , maintain eye contact
and try not to pause ur speech.
Cox I did got nervous during the interview and pause my speech
during the start of the interview.
1 of the interviewer actually gave me chance and told me not to
pause during the speech.
And throughout the whole interview process , I tried to talk as
much as I could and not pausing my speech.
And since u only hab ntc2 cert , be prepare for question like
"are u intending to further ur studies?"
Rmb dun gib answer like maybe or dunno.
