I've got to get this job!I need your help! FAST

[Flower]

Hi - I've got a 2nd interview next week and I have to do a 15 minute presentation on 'what will be my focus during the 1st 6 months of my job'. Do I need to get to specifics of the job role with my ideas - there are others doing the same job as I'll be doing so I don't want to undermine them and blast in with all of these new ideas or shall I just stick to me? Could anyone give me some good pointers to start off. I was going to back this up with a powerpoint presentation? Thank you!
