but can't get a visa to travel to us for my training I was refused the last time I went to the embassy that was in September
You are omitting half the facts here and folk are having to try second guess.
What was the reason that the US Embassy gave you for refusing entry?
please I need advise on how to go about the next interview
What you cannot do is to lie or mislead..
If you do and are caught, then any resultant visa will be terminated.
