Job-Interview Question: Would You Rather Work from Home or the Office?

There's no research to do in order to answer this question.

If you'd rather work from home, this is the time to say so because this is the time for both parties to figure out if they'd be happy with each other.

Of course, and as always, do show that you're professional and flexible by adding that you'd of course still go to office if needed.

At my discretion.
