You have three switches in one room and a single light bulb in another room. You are allowed to visit the room with the light bulb only once. How do you figure out which switch controls the bulb? Write your answer in the comments before looking at other answers.

If this were an interview question, the correct response would be "Do you have any relevant questions for me? Because have a long list of things that more deserving of my precious time than to think about this!
Stupid interview questions show you nothing about how people think. Might as well ask them their astrological animal and blood type
Telling me your blood type or astrological signs is as useful as telling me your certifications and years of experience, these days.
On the contrary, someone can learn a lot from a question like this. If they immediately spit out the answer, then I know that they studied and came prepared to answer common questions like that. If they give a response like the OP, then I know they are an asshole to work with. If they don’t know, do they ask follow up questions or ask for a moment to think can tell me how well they like to work in a group. If they talk about asking a coworker vs researching a solution independently first can tell me how they may react to a brick wall of a problem. Last thing that comes to my mind, is how long they try before giving up. That can be a good indicator for how they treat work meetings - do they push through the task one at a time and in exact order, or do they have the social skills to know when it is time to shut up and move on to the next thing.
The problem is that it sounds like a riddle. In a riddle, you’re traditionally supposed to work within the rules that you’ve been told. So, not thinking outside the box here is not an indication that the person isn’t capable of doing so.
Of course, if I encountered this problem in real life, I’d ask Carol from accounting to check the other room, while I flip the switches. But my instinctive answer was that it is not possible, because I assumed it to be a riddle and the provided rules did not allow a solution.
