Suppose your company is growing fast and you need to hire more developers. A candidate comes along and asks all kinds of question about tests and documentation and all that boring stuff. You know there are some pretty serious deficiencies, but you don't want to scare away the candidate. On the other hand, nobody likes to be subject to a bait-and-switch.
So how much should you reveal as a technical interviewer when the candidate decides to be the one asking the questions, and is there a good way to go about it?
