I'm trying to transfer from one field (which I've worked in for nearly a decade) to a related one. I've been asked in interviews why I want to do that and I never know how to answer without sounding insincere.
My real reasons are that the field I'm trying to go into is better paid and more secure, compared to the industry I'm in now, which is lower paid and there are lay-offs all the time. But I feel like saying this would be frowned upon as the interviewers would think I only want the job for the money and because my first choice of career didn't work out as planned (which tbh is pretty accurate but...I can't say that).
On the other hand it just sounds naff if I give them the cliches about having a passion for the work (it's not a vocation-type career).
I'm rubbish at interviews in general but know I can do the work, I studied for a qualification to retrain and got some work experience through volunteering.
