As the hiring manager for a forensic science position, one unique interview question I would ask is, "Can you tell me about a time when you had to solve a problem with limited information?" This question is great because forensic science often involves piecing together clues from small bits of evidence, so it shows how a candidate thinks critically and creatively under pressure.
For a filter question on an application, I would use, "Do you have experience working in a lab environment or handling evidence?" This is important because it directly relates to the skills needed for the job, and it helps weed out applicants who may not have the necessary background in forensic science.
