One of the online interview questions was something like: What was a difficult challenge that I faced?

Nothing out of the ordinary really. They did want a detailed/lengthy explanation of all the duties performed at each position listed on my resume, some dating back 20 years. The information on the resume needed to be fully explained. I guess the most difficult question was when they gave a salary range and asked what I was looking for, I chose a number close to the top of that range based on my experience. I now understand this is a "no-no" in job hunting these days but I had just gotten back into the hunt after 10 years in the same position and what they offered was still $15k less than I was making. I was asked would I consider taking less. When I refused, they asked why.
