If you need inspiration to ask the salary question, just think about a plumber.
The plumber isn’t going to come over and walk around looking at the work that a homeowner needs done without talking about money. Eventually the plumber is going to say “You’re looking at about ten thousand dollars worth of work” or the homeowner is going to say “How much is this going to cost me?”
They’re not going to dance around the topic and hope for the best. Only job-seekers do that, and only a certain kind of job-seeker.
You can’t keep going on interviews with no idea of what an employer is planning to pay you if you get the job. You have to bring up the topic of salary.
