It amazes me how many jobs are advertised without stating the salary or will say salary dependant on experience. I think that all jobs should give an idea of a salary on the advert even if it is just an approximation and is a band between two amounts.

No one can be expected to take a job without knowing what they will be earning but sometimes the salary is not even mentioned in an interview.

If you have applied for a job that does not state the salary and then you get called for an interview, then you will need to be prepared to ask. Do not make it your first question when in the interview, hold fire until the end as they may well cover salaries and holidays etc in the interview.  If when you find out the salary, it is too low for you, don’t feel bad about saying that unfortunately you would not be able to continue with the application as the salary is less than you were looking for. If you are the right candidate for them then you may find that they offer you more money.
