I had an interview for a permanent position in the team I had been contracting for. To make it harder, one of my (junior) coworkers was on the interview panel. When the HR person asked me what my salary expectations were, rather than name any numbers (which would have caused friction since I was making significantly more that the person in my team on the interview) my response was "I know what the salary bands for POSITION and senior POSITION are. I think with my skills and experience I am in the middle to slightly above the midpoint of the senior POSITION salary band."

My team lead was really happy with that response and the offer I got was at the top of the senior POSITION band.
