Cowen's recommendation: "What are the open tabs in your browser right now?"
First, the question measures what a person does with his or her spare time as well as work time. If you leave a browser tab open, it probably has some importance to you and you expect to return to the page. It is one metric of what you are interested in and what your work flow looks like.
It’s not just cheap talk. Some job candidates might say they are interested in C++ as a programming language, but if you actually have an open page to the Reddit and Subreddits on that topic, that is a demonstrated preference...
The question also tests for enthusiasm. If the person doesn’t seem excited about any of those open browser tabs, that may be a sign that they are blasé about other things as well. But if you get a heated pitch about why a particular website is the best guide to “Lord of the Rings” lore, you may have found a true nerd with a love of detail. That will be a plus for many jobs and avocations, though not all.
