I receive a job offer from a Ministry but I prefer another job from Stats Board, but the Stats Board have not call me for an interview. The status updated in Career@Gov for the Stats Board position was "In Process".

Under this situation, can I agree to accept the offer from Ministry first, while waiting for the Stats Board interview? If Stats board offers me the job, then I inform the Ministry that I have better offer? I know this will not appear good in me, but I don't dare to take the risk to reject the Ministry, just in case the Stats Board did not call me for interview or I was not selected for the job. Anyone have experience similar situation before? Can give some advice? I'm really lost now..
