You can ask for the salary range from the recruiter. Here’s the challenge. I’m not sure if the California law applies to companies or applicants, bc you’re out of state.... maybe research that to start?
The good thing is that bc you essentially have an offer in the bag, the recruiter is unlikely to rescind an offer bc you’re adventurous in asking. :).
The recruiter can’t say, they asked me the salary band, let’s go with plan B. The HM will tell the recruiter to suck it up and grow thick skin. Moving west is a big deal, I did it many years ago. I had no clue what I was in for.... the bay is expensive. The only cost that went down for me is taxi cost.... and not bc I’m at Uber. Lol.
