Get in touch with the recruitment dept and ask to amend the date. I'm an NHS manager and have interviewed over a couple of days to accommodate a similar incidence. I think it's down to the interviewer if they are willing to do it or not. Good luck for your interview 🙂
I have recieved an invitation to attend an interview on a certain date (the interview date was not specified on the job advert) but I am unable to attend due to preexisting work commitments. The invitation only has the options to confirm the date and set a time or decline and withdraw application. Will it be possible to have the date changed? And if so, how do I go about it?
