New job & interview

[mammasmadhouse]

I am looking to leave my current role despite only being in post for 2 months. I had a run in with the acting boss as I didn?t agree with something she was doing; admittedly she changed her direction slightly after this. But it just doesn?t sit right, she is constantly talking about changing my role and I find it all too unnerving and uncomfortable. Yes I accept that job roles changes and you do naturally take on other tasks along the way but let me do the job I applied for a little while at least. Apologies for the waffle, my question is I have an interview coming up how do I explain wanting to move after such a short space of time??
The post I have an interview is more hours but I really don?t want to cock it up!!!

That you saw this job and had to apply for it because it looks to be ...........

That the job has turned out to be different from that advertised. Be careful to phrase things in as positive a way as possible. EG, explain "I was attracted to the job because I could use my experience in XYZ, however as soon as I arrived there was a reorganisation and in my current role I'm not using all of my expertise / I'm not working at the level I am capable of / etc. However, this role [the you are applying for] appears to offer an opportunity to bring my skills to it and develop myself blah blah..."
