I've been in my current role for 3.5 months as part of a 12 month secondment which has not been how I expected it to be (low workload, disorganised department) and I'm not entirely happy. I'm not going back to my 'home' role either due to the anxiety and stress I faced whilst in that role, so I've decided to look for another job.
I have an interview on Friday (external company), and they will more than likely ask me why I want to leave my current role, but I'm not quite sure what to say! Do I mention that I'm on secondment? I didn't put the secondment role on my CV as it's the same job title as my 'home' role, but I have a lot of tasks on my CV under the 'home' role so it might seem weird if I say that role wasn't busy (which it was).
Any suggestions?
