Hi emma, I had an interview several weeks ago and they asked questions regarding my hons project (know this inside out) and some others on a research placement I organised. the usual other q's will probably come up why this project why here etc.. and rea the literature around the subject, primarily on some of the methods used and key results, and find out who is top in the field you are going into. these may come up but its a starting point, be very confident ..you want to publish publish publish, this will get you some extra interest.
