7. "What's your vacation policy, because I have this trip I'm taking next month..."
This one is similar to the salary discussion, except the other extreme.
Again, this isn’t a bad question to ask – down the road a bit! But if the first question you have for them is whether you can get extra time off for a job that you don’t even have yet, that’s going to be seen as a deterrent.
Once you get into the interview process a little bit more and determine whether they are seriously considering hiring you (and whether you want to work there), then you should start talking about specifics. Don’t forget to use things like vacation time as leverage if the company won’t budge on salary. But whatever you do, just don’t jump the gun and cost yourself a good opportunity.
