Interview - salary not disclosed. Once bitten, twice shy

[Peanutsthemonkey]

I have been invited to an interview for a role in which no salary was advertised. Previously at this stage when I have asked, businesses have disclosed it, or a range so I am happy to interview. I am asking as I'm wary - in my current job they said we will discuss at interview to which after accepting the job I feel a bit shafted as others in same role are on more despite my experience...
If they don't want to disclose this how can I say politely thanks for the interview offer but no thanks and this is why. Basically once bitten twice shy. Btw this isn't a niche or high level job so no reason to hide it. It is also a very large, respected business.

in my current job they said we will discuss at interview to which after accepting the job I feel a bit shafted as others in same role are on more despite my experience...

All that means is that the others in that role were better at negotiating their salary than you were.

If they disclose a range, they will probably try and start you on as low as they can get away with, it's then up to you to negotiate higher.

I know you're right and that's what my current job has done. I've also now found that when they've been in need of filling a job they're happy to pay more for someone with no experience....it does feel personal though when this is happening and they're being paid more than you, but yes that person asked and got what they wanted.
I just don't see how you can negotiate when there's little to benchmark against, yes other businesses but theres many factors that come along with that too...at least with a range you could say I've lots of experience I can try for the top or I've little, so expect the bottom.

It is generally shit that the salary is based on something which has very little relevance to the job (unless the job is about money/negotiation).

Maybe something like Happy to hear you are invited, could they share the salary range, so you'll not waste both your and their time if the salary range won't work?
and maybe combine it with one more, easier question, so it won't be "only about money".

Why bother with a job ad that doesn't have a salary on?

I wouldn't

@ZiriForEver thanks, I didn't want it to come across as all about the money...its not of course but it is an important factor.

@DuesExMachina normally I don't and after my current role said never again but this is a well known employer so good opportunity but of course depends on the £

I have said before we go any further I will be expecting at least 60k are we in the same ballpark? Better for everyone to know upfront

You must be able to get some loose sense of what the going rate is across the industry. Yes there are differences in conditions and some companies do just pay better than others. But you must be able to benchmark the salary expectations for the role.
