Always ask if there is an incumbent who is currently acting in the position before you apply or else you are just wasting your time! Make up a story for the questions because no one will actually check with your former employer whether it was based in reality.
Follow the STAR method interview approach and be up to date about Indigenous knowledge.
Do your homework. One position can have 300+ applicants. The one who gets the job is the one who does their homework/research/prep.
