I'm in an awkward situation. I applied for an internal position at my company for a slight promotion from my current role. It would be within the same department. The management structure of my department suddenly changed today and due to this change I am no longer interested in the role. I would really like to stay in my current role. My interview is set for Monday and I am wondering how best to approach this situation in a professional manner without tarnishing my current role and reputation. I am hoping there is a correct answer on how to approach this.
Interview as if I am still interested and then turn down the offer if offered?
Attend the interview and use it as an opportunity to explain that I am no longer interested and why?
Email my director and HR rep this weekend to announce that I am no longer interested and would like to retract my application, and explain why?
Email my director and HR rep this weekend to ask for a meeting Monday morning to discuss the concerns I have in proceeding with the interview for this role.
A combo of the last two?
I feel I have good reason for my change of mind and that they will be understanding. I would like to also save everyone's time and effort, but would like to do so in a professional way that doesn't look bad on me or my current role.
