We're interviewing for a senior role. Salary was clearly mentioned in the job posting (I double checked this today). However, once we gave the verbal offer he mentioned the salary was below his expectations, but he already knew it, so can't claim ignorance.
We have a close second who I assume would be ok with the salary that was actually posted...
I know potentially we can go a bit higher BUT that was the total compensation, whereas what we were offering could.potentially be higher based on a performance bonus.
