Extractable interview questions

After sending my resume, I received an email offering to do a phone interview in the next few days. Did the phone interview (30-40 min) on a friday and I was told they will be in contact in the next few days. Indeed they contacted me the following thursday.

Overall this was a pretty typical and easy interview process. 1 phone screen, then an onsite with three individual interviews. The first two people I met with in person were fine. They were both friendly and personable, and had pretty typical interview questions. The final person I met with was not part of their design hierarchy. As far as I can tell, the whole reason she came in to interview me at all was to just immediately try to downplay my skills and experience as not valuable, and basically badger me about salary. Ultimately I was given an offer for a contract position, and they wanted to open conversation about hourly rates. I sent them an opening rate, a week goes by, I hear nothing. I email them, another week goes by, I hear nothing again. Then I get a reply that they have decided to rescind the offer with no reason given. It really seems like they were trying to lock me up for a few weeks while they were still weighing other options, which is a pretty shady move.
