Suggested approach: iBeacons were introduced way back in iOS 7, and have found mixed use – unless you’re applying for an iBeacon development job this is one you can probably skip with “I haven’t used them much, but I’m keen to learn!”
Of course, if you do have experience then this is your time to shine: talk about major and minor identifiers, talk about positioning beacons overhead to avoid interference from people and devices, talk about ranging, and more.
Estimated difficulty: Intermediate
