You have the right to confirm likely salary offer after interview number two.
Unfortunately there’s a really strange thing that happens in very long interview processes, is the employer starts to think something is wrong because the process has taken so long, despite the process being driven by them.
Anyhow, to your situation…. It is now an employers market and some of them need to feel loved.
So you should effusively tell them that you love the company and love the job.
