pls help..I have an interveiw with behavioral health unit

I have gone to interviews wearing a uniform, but that was because I had to go to my regular job soon afterwards. I made sure that it was crisp white, so that they would have an image of how professional I would look on the ward. If this is not the case with you, then, wear business attire...not too much makeup, not too flashy, or look like you are going to a party.

What I would do, is review things in my textbook about behavioral health, or psychiatry, and emphasize reading on certain points, such as how to deal with certain behaviors...opening up pills in front of paranoid patients, to decrease suspicion, to allow obsessive-compulsive to complete their rituals to reduce their anxieities, and read about their most common medications. Good luck!
