During a phone interview, I was asked what my preferred pay range was. When I answered, he kept asking me where else I had been applying/interviewing. I gave general examples of the offers I had been receiving, to which he kept asking more questions trying to get specifics out of me. And then, while I was mid-sentence, the recruiter asked if he could call me back in 5-10 minutes. I was a bit taken aback but said okay.... even though it felt very unprofessional for him to hang up on me mid-interview. He called me back 4 hours later. I was really annoyed but finished the interview. One of the worst interview experiences I've had in a long while. I wish companies would remember that we are interviewing them as much as they are interviewing us.
