Difficulty: Medium

Rounds: 1-2 (Phone screening followed by in-person implied)

Topics Asked: Order of tubes, greatest weakness, function of blood cultures, specific tubes for CBC/PTT/PT, youngest draw performed, "Tell me about yourself," needle choice for antecubital area, handling requisition forms.

Experience:

The interview included several technical phlebotomy questions. Candidates were asked about the order of tubes for blood draws (e.g., green top, blue, lavender, gold top) and what each tube is used for (e.g., what blood cultures do, which tube is for CBC, PTT, and PT). Behavioral questions included "What is your greatest weakness?" and "Tell me about yourself." The interviewer also probed practical experience with questions like "What is the youngest draw you have done?" and "What needle do you use in the antecubital area?" There was also a scenario-based question: "Like a patient comes in with this requisition form, what would you do, etc." One commenter in the thread mentioned passing the interview.
