general approach to testing products.
An alternative is to describe your product. Then ask the tester about his or her approach to testing the product or a piece of the product. If you have the time, follow up with a behavior-description question, such as "Have you ever tested a product in this way before?" Follow the story of how the tester tested the product.
Wrap Up the Phone Screen
As soon as you know the candidate isn't a good fit, say so. "You're not a good fit for this position. Thank you for your time."
But, if you have a candidate who fits, make sure you ask questions about the candidate's time frame and willingness to interview. If you're hiring someone fresh out of college, you may need to wait a while before he or she is available to start. Schedule the in-person interview at the end of the phone screen, or the next day.
Phone screens take more of the hiring manager's time, but significantly less of the interviewing team's time. Plus, you'll know before the interview that you're spending time with a candidate who is suitable for your position.
