How to run a Zero-Waste Supply Chain Optimizer pre-screening interview

  1. 1
    Select 6–8 questions from the list below

    Pick a mix of question types — at least one about background and track record, two behavioral questions asking for specific past examples, and one situational or motivation question. Avoid asking all 20 — focused calls produce better, more comparable answers across candidates.

  2. 2
    Block a consistent 20–30 minute time slot

    Consistent duration keeps comparisons fair. Inform candidates of the time commitment in the invite so they come prepared, not rushed.

  3. 3
    Score on a 1–5 scale per question, immediately after the call

    Define what strong, average, and weak answers look like before the first call. Score within five minutes of hanging up — memory degrades fast across multiple candidate conversations.

  4. 4
    Advance candidates above a pre-set minimum threshold

    Set the pass score before your first call, not after reviewing results. This is the single most effective way to remove unconscious bias from the screening stage.

Skip the manual calls entirely. InterviewFlowAI conducts the entire pre-screening conversation via AI phone or video call, asks adaptive follow-up questions, and delivers a scored report instantly. $0.99 per candidate. No human required on the call.
