I was tossing up whether to accept the interview or not but see it as me finding out if I am interested. They didn't give much information about work patterns, workload or how it might work for me and I can see that the only way is to find out at interview.
Is it bad to go for a job and do the interview knowing it is unlikely you will accept? And can turning it down be done without burning bridges?
(No, it is not fait accompli' but nervous)
