This is a great question to use when you’re interviewing someone and trying to learn more about them. It can give you insights into how they work, what their routine looks like and what is important at the moment to them. It’s also uncommon enough to get them out of the usual interview mode and into a more open frame of mind. I will suggest however that you only use on people who are willing to live out loud and won’t be put out by such a personal question.
A good variation on this would be to share 3 tabs they have open, of their choosing Or, the last thing they Googled for reference.
