A couple of points...
...there are situations, although extrordinarily rare, where an abort after V1 would be appropriate (a jammed elevator comes to mind). Generally speaking you should fly the profile as taught and breifed though.
...when answering these questions don't ever tell an interviewer that you will break company policy or FAA regulations, no matter how much they lead you down that road. There are jobs where creativity would be a plus, piloting is not one of those jobs. A company wants all of it's pilots to do everything standard and consistant. Trying to get everyone at a particular company to do that is a challenge.
...also, if you go over the possibilities of a particular situation before answering the question you will show the interviewer that you can think on the fly (even though you have been thinking about the question for weeks after reading it on a gouge website). For example, in the ILS at minimums question it's possible that the Captain has lost his marbles and is hurdling the airplane at the ground with nothing in sight, it's also possible that he doesn't realize that you are at minimums (some of those old guys are a little hard of hearing), it's possible that he's incapacitated, and it's even possible that he really sees the "runway environment", but you don't (think large crosswind), there are probably more possibilities that I can't think of. A quick and simple solution (be careful, this is my answer not necessarily yours) is to question the captain by saying "Minimums, where's the runway?". If he answers "11 o'clock low", and you look and see it, you are landing and you avoided a conflict. If he answers "I don't see it, I want to take a look", it is time to tell the tower that you don't see the runway and are going around, if he keeps going it may be time to take the airplane (beats hitting the ground right?). If he doesn't answer, ask again and if still no reply take the controls assuming he is incapacitated. Though this answer took a fair amount of time to read and your answer will take a fair amount of time to say, in practice it takes very little time and shows that you have a plan for a very critical situation. Good luck.
