A contract hiring company handles the phone interview. They must have your resume, but the first half was asking several questions again to get the job history (including job titles, name and location of previous employers, time period worked there.) They also asked for contacts at each location, so have all that ready. The second half was inquiring about your experience with specific tasks and lab procedures. They went through a list of equipment/assays/functions and all you have to do is say whether you have experience with them or not and if so, how much (knowledge of, hands on, etc.)
