I have an interview at the start of December and it is my first interview in 16 years (unless you count internal interviews).
For various reasons I want to leave my current employer (who I've been with for 16 years) but I have a very good salary and benefits package here.
The job I'm applying for has a salary scale but doesn't say "successful applicants will start at the bottom....blah blah". It is public sector. (I am in public sector already but a different company and sector.)
On the application form, it asked for current salary and I kept this blank because I thought a, it might put them off me and b, I really want to leave my current employer that I thought I wouldn't mind a pay cut.
I'm currently in the middle of that salary scale and whilst I wouldn't mind a small drop in salary, I couldn't start at the very beginning. Reality has kicked in and whilst my current employer is making me ill (literally), my initial thinking that happiness is more important is probably wrong. I don't want to have to watch the pennies. And there would be that sense of failure if I took that much of a drop 
WIBU to contact the interviewer and ask if the salary would be negotiable? I don't want to waste mine or their time? Would that ruin any chance of getting the role? I know in my company that incoming employees cannot negotiate. The salary is what it is.
I also think the job involves a lot more work than I'm doing in my current role too.
Jobs in this area are very hard to find too.
