Some of the 1500hr pilots do have jet time, For those without jet time, they are not looking at you to nail it, they want to see your basic instrument skills are up to par. If I didnt have any jet time I would probably invest in some time in a sim (I saw a television commercial while I was on the road about a "Date Night Flight Sim" experience, not sure where). You will also need to have your ATP/CTP done which gives you some sim time. At least for us, the last day we were asked "what else would you like to try", V1 cuts are not that bad, most people struggle becasue they overthink it. Keep your eyes outside and do what you would normally do, plane going off to the left, add right rudder to stay on the centerline (Hint, you will need most, if not all of the rudder), get the plane under control and rotate.
